+==============================================================================
+1. Introduction						*edit-intro*
+
+Editing a file with Vim means:
+
+1. reading the file into a buffer
+2. changing the buffer with editor commands
+3. writing the buffer into a file
+
+							*current-file*
+As long as you don't write the buffer, the original file remains unchanged.
+If you start editing a file (read a file into the buffer), the file name is
+remembered as the "current file name".  This is also known as the name of the
+current buffer.  It can be used with "%" on the command line |:_%|.
+
+							*alternate-file*
+If there already was a current file name, then that one becomes the alternate
+file name.  It can be used with "#" on the command line |:_#| and you can use
+the |CTRL-^| command to toggle between the current and the alternate file.
+However, the alternate file name is not changed when |:keepalt| is used.
+An alternate file name is remembered for each window.
+
+							*:keepalt* *:keepa*
+:keepalt {cmd}		Execute {cmd} while keeping the current alternate file
+			name.  Note that commands invoked indirectly (e.g.,
+			with a function) may still set the alternate file
+			name.
+
+All file names are remembered in the buffer list.  When you enter a file name,
+for editing (e.g., with ":e filename") or writing (e.g., with ":w filename"),
+the file name is added to the list.  You can use the buffer list to remember
+which files you edited and to quickly switch from one file to another (e.g.,
+to copy text) with the |CTRL-^| command.  First type the number of the file
+and then hit CTRL-^.
+
+
+CTRL-G		or				*CTRL-G* *:f* *:fi* *:file*
+:f[ile]			Prints the current file name (as typed, unless ":cd"
+			was used), the cursor position (unless the 'ruler'
+			option is set), and the file status (readonly,
+			modified, read errors, new file).  See the 'shortmess'
+			option about how to make this message shorter.
+
+:f[ile]!		like |:file|, but don't truncate the name even when
+			'shortmess' indicates this.
+
+{count}CTRL-G		Like CTRL-G, but prints the current file name with
+			full path.  If the count is higher than 1 the current
+			buffer number is also given.
+
+					*g_CTRL-G* *word-count* *byte-count*
+g CTRL-G		Prints the current position of the cursor in five
+			ways: Column, Line, Word, Character and Byte.  If the
+			number of Characters and Bytes is the same then the
+			Character position is omitted.
+
+			If there are characters in the line that take more
+			than one position on the screen (<Tab> or special
+			character), or characters using more than one byte per
+			column (characters above 0x7F when 'encoding' is
+			utf-8), both the byte column and the screen column are
+			shown, separated by a dash.
+
+			Also see the 'ruler' option and the |wordcount()|
+			function.
+
+							*v_g_CTRL-G*
+{Visual}g CTRL-G	Similar to "g CTRL-G", but Word, Character, Line, and
+			Byte counts for the visually selected region are
+			displayed.
+			In Blockwise mode, Column count is also shown.  (For
+			{Visual} see |Visual-mode|.)
+
+							*:file_f*
+:f[ile][!] {name}	Sets the current file name to {name}.  The optional !
+			avoids truncating the message, as with |:file|.
+			If the buffer did have a name, that name becomes the
+			|alternate-file| name.  An unlisted buffer is created
+			to hold the old name.
+							*:0file*
+:0f[ile][!]		Remove the name of the current buffer.  The optional !
+			avoids truncating the message, as with |:file|.
+
+:buffers
+:files
+:ls			List all the currently known file names.  See
+			|windows.txt| |:files| |:buffers| |:ls|.
+
+Vim will remember the full path name of a file name that you enter.  In most
+cases when the file name is displayed only the name you typed is shown, but
+the full path name is being used if you used the ":cd" command |:cd|.
+
+							*home-replace*
+If the environment variable $HOME is set, and the file name starts with that
+string, it is often displayed with HOME replaced with "~".  This was done to
+keep file names short.  When reading or writing files the full name is still
+used, the "~" is only used when displaying file names.  When replacing the
+file name would result in just "~", "~/" is used instead (to avoid confusion
+between options set to $HOME with 'backupext' set to "~").
+
+When writing the buffer, the default is to use the current file name.  Thus
+when you give the "ZZ" or ":wq" command, the original file will be
+overwritten.  If you do not want this, the buffer can be written into another
+file by giving a file name argument to the ":write" command.  For example: >
+
+	vim testfile
+	[change the buffer with editor commands]
+	:w newfile
+	:q
+
+This will create a file "newfile", that is a modified copy of "testfile".
+The file "testfile" will remain unchanged.  Anyway, if the 'backup' option is
+set, Vim renames or copies the original file before it will be overwritten.
+You can use this file if you discover that you need the original file.  See
+also the 'patchmode' option.  The name of the backup file is normally the same
+as the original file with 'backupext' appended.  The default "~" is a bit
+strange to avoid accidentally overwriting existing files.  If you prefer ".bak"
+change the 'backupext' option.  Extra dots are replaced with '_' on MS-Windows
+machines, when Vim has detected that an MS-DOS-like filesystem is being used
+(e.g., messydos or crossdos) or when the 'shortname' option is on.  The
+backup file can be placed in another directory by setting 'backupdir'.
+
+							*auto-shortname*
+Technical: On the Amiga you can use 30 characters for a file name.  But on an
+	   MS-DOS-compatible filesystem only 8 plus 3 characters are
+	   available.  Vim tries to detect the type of filesystem when it is
+	   creating the .swp file.  If an MS-DOS-like filesystem is suspected,
+	   a flag is set that has the same effect as setting the 'shortname'
+	   option.  This flag will be reset as soon as you start editing a
+	   new file.  The flag will be used when making the file name for the
+	   ".swp" and ".~" files for the current file.  But when you are
+	   editing a file in a normal filesystem and write to an MS-DOS-like
+	   filesystem the flag will not have been set.  In that case the
+	   creation of the ".~" file may fail and you will get an error
+	   message.  Use the 'shortname' option in this case.
+
+When you started editing without giving a file name, "No File" is displayed in
+messages.  If the ":write" command is used with a file name argument, the file
+name for the current file is set to that file name.  This only happens when
+the 'F' flag is included in 'cpoptions' (by default it is included) |cpo-F|.
+This is useful when entering text in an empty buffer and then writing it to a
+file.  If 'cpoptions' contains the 'f' flag (by default it is NOT included)
+|cpo-f| the file name is set for the ":read file" command.  This is useful
+when starting Vim without an argument and then doing ":read file" to start
+editing a file.
+When the file name was set and 'filetype' is empty the filetype detection
+autocommands will be triggered.
+							*not-edited*
+Because the file name was set without really starting to edit that file, you
+are protected from overwriting that file.  This is done by setting the
+"notedited" flag.  You can see if this flag is set with the CTRL-G or ":file"
+command.  It will include "[Not edited]" when the "notedited" flag is set.
+When writing the buffer to the current file name (with ":w!"), the "notedited"
+flag is reset.
+
+							*abandon*
+Vim remembers whether you have changed the buffer.  You are protected from
+losing the changes you made.  If you try to quit without writing, or want to
+start editing another file, Vim will refuse this.  In order to overrule this
+protection, add a '!' to the command.  The changes will then be lost.  For
+example: ":q" will not work if the buffer was changed, but ":q!" will.  To see
+whether the buffer was changed use the "CTRL-G" command.  The message includes
+the string "[Modified]" if the buffer has been changed, or "+" if the 'm' flag
+is in 'shortmess'.
+
+If you want to automatically save the changes without asking, switch on the
+'autowriteall' option.  'autowrite' is the associated Vi-compatible option
+that does not work for all commands.
+
+If you want to keep the changed buffer without saving it, switch on the
+'hidden' option.  See |hidden-buffer|.  Some commands work like this even when
+'hidden' is not set, check the help for the command.
+
+==============================================================================
+2. Editing a file					*edit-a-file*
+
+							*:e* *:edit* *reload*
+:e[dit] [++opt] [+cmd]	Edit the current file.  This is useful to re-edit the
+			current file, when it has been changed outside of Vim.
+			This fails when changes have been made to the current
+			buffer and 'autowriteall' isn't set or the file can't
+			be written.
+			Also see |++opt| and |+cmd|.
+
+							*:edit!* *discard*
+:e[dit]! [++opt] [+cmd]
+			Edit the current file always.  Discard any changes to
+			the current buffer.  This is useful if you want to
+			start all over again.
+			Also see |++opt| and |+cmd|.
+
+							*:edit_f*
+:e[dit] [++opt] [+cmd] {file}
+			Edit {file}.
+			This fails when changes have been made to the current
+			buffer, unless 'hidden' is set or 'autowriteall' is
+			set and the file can be written.
+			Also see |++opt| and |+cmd|.
+
+							*:edit!_f*
+:e[dit]! [++opt] [+cmd] {file}
+			Edit {file} always.  Discard any changes to the
+			current buffer.
+			Also see |++opt| and |+cmd|.
+							*:edit_#* *:e#*
+:e[dit] [++opt] [+cmd] #[count]
+			Edit the [count]th buffer (as shown by |:files|).
+			This command does the same as [count] CTRL-^.  But ":e
+			#" doesn't work if the alternate buffer doesn't have a
+			file name, while CTRL-^ still works then.
+			Also see |++opt| and |+cmd|.
+
+							*:ene* *:enew*
+:ene[w]			Edit a new, unnamed buffer.  This fails when changes
+			have been made to the current buffer, unless 'hidden'
+			is set or 'autowriteall' is set and the file can be
+			written.
+			If 'fileformats' is not empty, the first format given
+			will be used for the new buffer.  If 'fileformats' is
+			empty, the 'fileformat' of the current buffer is used.
+
+							*:ene!* *:enew!*
+:ene[w]!		Edit a new, unnamed buffer.  Discard any changes to
+			the current buffer.
+			Set 'fileformat' like |:enew|.
+
+							*:fin* *:find*
+:fin[d][!] [++opt] [+cmd] {file}
+			Find {file} in 'path' and then |:edit| it.
+
+:{count}fin[d][!] [++opt] [+cmd] {file}
+			Just like ":find", but use the {count} match in
+			'path'.  Thus ":2find file" will find the second
+			"file" found in 'path'.  When there are fewer matches
+			for the file in 'path' than asked for, you get an
+			error message.
+
+							*:ex*
+:ex [++opt] [+cmd] [file]
+			Same as |:edit|.
+
+							*:vi* *:visual*
+:vi[sual][!] [++opt] [+cmd] [file]
+			When used in Ex mode: Leave |Ex-mode|, go back to
+			Normal mode.  Otherwise same as |:edit|.
+
+							*:vie* *:view*
+:vie[w][!] [++opt] [+cmd] file
+			When used in Ex mode: Leave |Ex-mode|, go back to
+			Normal mode.  Otherwise same as |:edit|, but set
+			'readonly' option for this buffer.
+
+							*CTRL-^* *CTRL-6*
+CTRL-^			Edit the alternate file.  Mostly the alternate file is
+			the previously edited file.  This is a quick way to
+			toggle between two files.  It is equivalent to ":e #",
+			except that it also works when there is no file name.
+
+			If the 'autowrite' or 'autowriteall' option is on and
+			the buffer was changed, write it.
+			Mostly the ^ character is positioned on the 6 key,
+			pressing CTRL and 6 then gets you what we call CTRL-^.
+			But on some non-US keyboards CTRL-^ is produced in
+			another way.
+
+{count}CTRL-^		Edit [count]th file in the buffer list (equivalent to
+			":e #[count]").  This is a quick way to switch between
+			files.
+			See |CTRL-^| above for further details.
+
+[count]]f						*]f* *[f*
+[count][f		Same as "gf".  Deprecated.
+
+							*gf* *E446* *E447*
+[count]gf		Edit the file whose name is under or after the cursor.
+			Mnemonic: "goto file".
+			Uses the 'isfname' option to find out which characters
+			are supposed to be in a file name.  Trailing
+			punctuation characters ".,:;!" are ignored. Escaped
+			spaces "\ " are reduced to a single space.
+			Uses the 'path' option as a list of directory names to
+			look for the file.  See the 'path' option for details
+			about relative directories and wildcards.
+			Uses the 'suffixesadd' option to check for file names
+			with a suffix added.
+			If the file can't be found, 'includeexpr' is used to
+			modify the name and another attempt is done.
+			If a [count] is given, the count'th file that is found
+			in the 'path' is edited.
+			This command fails if Vim refuses to |abandon| the
+			current file.
+			If you want to edit the file in a new window use
+			|CTRL-W_CTRL-F|.
+			If you do want to edit a new file, use: >
+				:e <cfile>
+<			To make gf always work like that: >
+				:map gf :e <cfile><CR>
+<			If the name is a hypertext link, that looks like
+			"type://machine/path", you need the |netrw| plugin.
+			For Unix the '~' character is expanded, like in
+			"~user/file".  Environment variables are expanded too
+			|expand-env|.
+
+							*v_gf*
+{Visual}[count]gf	Same as "gf", but the highlighted text is used as the
+			name of the file to edit.  'isfname' is ignored.
+			Leading blanks are skipped, otherwise all blanks and
+			special characters are included in the file name.
+			(For {Visual} see |Visual-mode|.)
+
+							*gF*
+[count]gF		Same as "gf", except if a number follows the file
+			name, then the cursor is positioned on that line in
+			the file.
+			The file name and the number must be separated by a
+			non-filename (see 'isfname') and non-numeric
+			character. " line " is also recognized, like it is
+			used in the output of `:verbose command UserCmd`
+			White space between the filename, the separator and
+			the number are ignored.
+			Examples:
+				eval.c:10 ~
+				eval.c @ 20 ~
+				eval.c (30) ~
+				eval.c 40 ~
+
+							*v_gF*
+{Visual}[count]gF	Same as "v_gf".
+
+These commands are used to start editing a single file.  This means that the
+file is read into the buffer and the current file name is set.  The file that
+is opened depends on the current directory, see |:cd|.
+
+See |read-messages| for an explanation of the message that is given after the
+file has been read.
+
+You can use the ":e!" command if you messed up the buffer and want to start
+all over again.  The ":e" command is only useful if you have changed the
+current file name.
+
+							*:filename* *{file}*
+Besides the things mentioned here, more special items for where a filename is
+expected are mentioned at |cmdline-special|.
+
+Note for systems other than Unix: When using a command that accepts a single
+file name (like ":edit file") spaces in the file name are allowed, but
+trailing spaces are ignored.  This is useful on systems that regularly embed
+spaces in file names (like MS-Windows and the Amiga).  Example: The command
+":e   Long File Name " will edit the file "Long File Name".  When using a
+command that accepts more than one file name (like ":next file1 file2")
+embedded spaces must be escaped with a backslash.
+
+						*wildcard* *wildcards*
+Wildcards in {file} are expanded, but as with file completion, 'wildignore'
+and 'suffixes' apply.  Which wildcards are supported depends on the system.
+These are the common ones:
+	?	matches one character
+	*	matches anything, including nothing
+	**	matches anything, including nothing, recurses into directories
+	[abc]	match 'a', 'b' or 'c'
+
+To avoid the special meaning of the wildcards prepend a backslash.  However,
+on MS-Windows the backslash is a path separator and "path\[abc]" is still seen
+as a wildcard when "[" is in the 'isfname' option.  A simple way to avoid this
+is to use "path\[[]abc]", this matches the file "path\[abc]".
+
+					*starstar-wildcard*
+Expanding "**" is possible on Unix, Win32, macOS and a few other systems (but
+it may depend on your 'shell' setting on Unix and macOS. It's known to work
+correctly for zsh; for bash this requires at least bash version >= 4.X).
+This allows searching a directory tree.  This goes up to 100 directories deep.
+Note there are some commands where this works slightly differently, see
+|file-searching|.
+Example: >
+	:n **/*.txt
+Finds files:
+	aaa.txt ~
+	subdir/bbb.txt ~
+	a/b/c/d/ccc.txt ~
+When non-wildcard characters are used right before or after "**" these are
+only matched in the top directory.  They are not used for directories further
+down in the tree. For example: >
+	:n /usr/inc**/types.h
+Finds files:
+	/usr/include/types.h ~
+	/usr/include/sys/types.h ~
+	/usr/inc/old/types.h ~
+Note that the path with "/sys" is included because it does not need to match
+"/inc".  Thus it's like matching "/usr/inc*/*/*...", not
+"/usr/inc*/inc*/inc*".
+
+					*backtick-expansion* *`-expansion*
+On Unix and a few other systems you can also use backticks for the file name
+argument, for example: >
+	:next `find . -name ver\\*.c -print`
+	:view `ls -t *.patch  \| head -n1`
+Vim will run the command in backticks using the 'shell' and use the standard
+output as argument for the given Vim command (error messages from the shell
+command will be discarded).
+To see what shell command Vim is running, set the 'verbose' option to 4. When
+the shell command returns a non-zero exit code, an error message will be
+displayed and the Vim command will be aborted. To avoid this make the shell
+always return zero like so: >
+       :next `find . -name ver\\*.c -print \|\| true`
+
+The backslashes before the star are required to prevent the shell from
+expanding "ver*.c" prior to execution of the find program.  The backslash
+before the shell pipe symbol "|" prevents Vim from parsing it as command
+termination.
+This also works for most other systems, with the restriction that the
+backticks must be around the whole item.  It is not possible to have text
+directly before the first or just after the last backtick.
+
+						*`=* *E1083*
+You can have the backticks expanded as a Vim expression, instead of as an
+external command, by putting an equal sign right after the first backtick,
+e.g.: >
+	:e `=tempname()`
+The expression can contain just about anything, thus this can also be used to
+avoid the special meaning of '"', '|', '%' and '#'.  However, 'wildignore'
+does apply like to other wildcards.
+
+Environment variables in the expression are expanded when evaluating the
+expression, thus this works: >
+	:e `=$HOME .. '/.vimrc'`
+This uses $HOME inside a string and it will be used literally, most likely not
+what you intended: >
+	:e `='$HOME' .. '/.vimrc'`
+
+If the expression returns a string then names are to be separated with line
+breaks.  When the result is a |List| then each item is used as a name.  Line
+breaks also separate names.
+Note that such expressions are only supported in places where a filename is
+expected as an argument to an Ex-command.
+
+							*++opt* *[++opt]*
+The [++opt] argument can be used to force the value of 'fileformat',
+'fileencoding' or 'binary' to a value for one command, and to specify the
+behavior for bad characters.  The form is: >
+	++{optname}
+Or: >
+	++{optname}={value}
+
+Where {optname} is one of:	    *++ff* *++enc* *++bin* *++nobin* *++edit*
+    ff     or  fileformat   overrides 'fileformat'
+    enc    or  encoding	    overrides 'fileencoding'
+    bin    or  binary	    sets 'binary'
+    nobin  or  nobinary	    resets 'binary'
+    bad			    specifies behavior for bad characters
+    edit		    for |:read| only: keep option values as if editing
+			    a file
+
+{value} cannot contain white space.  It can be any valid value for these
+options.  Examples: >
+	:e ++ff=unix
+This edits the same file again with 'fileformat' set to "unix". >
+
+	:w ++enc=latin1 newfile
+This writes the current buffer to "newfile" in latin1 format.
+
+The message given when writing a file will show "[converted]" when
+'fileencoding' or the value specified with ++enc differs from 'encoding'.
+
+There may be several ++opt arguments, separated by white space.  They must all
+appear before any |+cmd| argument.
+
+								*++bad*
+The argument of "++bad=" specifies what happens with characters that can't be
+converted and illegal bytes.  It can be one of three things:
+    ++bad=X      A single-byte character that replaces each bad character.
+    ++bad=keep   Keep bad characters without conversion.  Note that this may
+		 result in illegal bytes in your text!
+    ++bad=drop   Remove the bad characters.
+
+The default is like "++bad=?": Replace each bad character with a question
+mark.  In some places an inverted question mark is used (0xBF).
+
+Note that not all commands use the ++bad argument, even though they do not
+give an error when you add it.  E.g. |:write|.
+
+Note that when reading, the 'fileformat' and 'fileencoding' options will be
+set to the used format.  When writing this doesn't happen, thus a next write
+will use the old value of the option.  Same for the 'binary' option.
+
+
+							*+cmd* *[+cmd]*
+The [+cmd] argument can be used to position the cursor in the newly opened
+file, or execute any other command:
+	+		Start at the last line.
+	+{num}		Start at line {num}.
+	+/{pat}		Start at first line containing {pat}.
+	+{command}	Execute {command} after opening the new file.
+			{command} is any Ex command.
+To include a white space in the {pat} or {command}, precede it with a
+backslash.  Double the number of backslashes. >
+	:edit  +/The\ book	     file
+	:edit  +/dir\ dirname\\      file
+	:edit  +set\ dir=c:\\\\temp  file
+Note that in the last example the number of backslashes is halved twice: Once
+for the "+cmd" argument and once for the ":set" command.
+
+							*file-formats*
+The 'fileformat' option sets the <EOL> style for a file:
+'fileformat'    characters	   name				~
+  "dos"		<CR><NL> or <NL>   DOS format		*DOS-format*
+  "unix"	<NL>		   Unix format		*Unix-format*
+  "mac"		<CR>		   Mac format		*Mac-format*
+Previously 'textmode' was used.  It is obsolete now.
+
+When reading a file, the mentioned characters are interpreted as the <EOL>.
+In DOS format (default for Win32), <CR><NL> and <NL> are both interpreted as
+the <EOL>.  Note that when writing the file in DOS format, <CR> characters
+will be added for each single <NL>.  Also see |file-read|.
+
+When writing a file, the mentioned characters are used for <EOL>.  For DOS
+format <CR><NL> is used.  Also see |DOS-format-write|.
+
+You can read a file in DOS format and write it in Unix format.  This will
+replace all <CR><NL> pairs by <NL> (assuming 'fileformats' includes "dos"): >
+	:e file
+	:set fileformat=unix
+	:w
+If you read a file in Unix format and write with DOS format, all <NL>
+characters will be replaced with <CR><NL> (assuming 'fileformats' includes
+"unix"): >
+	:e file
+	:set fileformat=dos
+	:w
+
+If you start editing a new file and the 'fileformats' option is not empty
+(which is the default), Vim will try to detect whether the lines in the file
+are separated by the specified formats.  When set to "unix,dos", Vim will
+check for lines with a single <NL> (as used on Unix and Amiga) or by a <CR>
+<NL> pair (MS-Windows).  Only when ALL lines end in <CR><NL>, 'fileformat' is
+set to "dos", otherwise it is set to "unix".  When 'fileformats' includes
+"mac", and no <NL> characters are found in the file, 'fileformat' is set to
+"mac".
+
+If the 'fileformat' option is set to "dos" on non-MS-Windows systems the
+message "[dos format]" is shown to remind you that something unusual is
+happening.  On MS-Windows systems you get the message "[unix format]" if
+'fileformat' is set to "unix".  On all systems but the Macintosh you get the
+message "[mac format]" if 'fileformat' is set to "mac".
+
+If the 'fileformats' option is empty and DOS format is used, but while reading
+a file some lines did not end in <CR><NL>, "[CR missing]" will be included in
+the file message.
+If the 'fileformats' option is empty and Mac format is used, but while reading
+a file a <NL> was found, "[NL missing]" will be included in the file message.
+
+If the new file does not exist, the 'fileformat' of the current buffer is used
+when 'fileformats' is empty.  Otherwise the first format from 'fileformats' is
+used for the new file.
+
+Before editing binary, executable or Vim script files you should set the
+'binary' option.  A simple way to do this is by starting Vim with the "-b"
+option.  This will avoid the use of 'fileformat'.  Without this you risk that
+single <NL> characters are unexpectedly replaced with <CR><NL>.
+
+You can encrypt files that are written by setting the 'key' option.  This
+provides some security against others reading your files. |encryption|
+
+END OF LINE AND END OF FILE				*eol-and-eof*
+
+Vim has several options to control the file format:
+	'fileformat'	the <EOL> style: Unix, DOS, Mac
+	'endofline'	whether the last line ends with a <EOL>
+	'endoffile'	whether the file ends with a CTRL-Z
+	'fixendofline'	whether to fix eol and eof
+
+The first three values are normally detected automatically when reading the
+file and are used when writing the text to a file.  While editing the buffer
+it looks like every line has a line ending and the CTRL-Z isn't there (an
+exception is when 'binary' is set, it works differently then).
+
+The 'fixendofline' option can be used to choose what to write.  You can also
+change the option values to write the file differently than how it was read.
+
+Here are some examples how to use them.
+
+If you want files in Unix format (every line NL terminated): >
+	setl ff=unix fixeol
+You should probably do this on any Unix-like system.  Also modern MS-Windows
+systems tend to work well with this.  It is recommended to always use this
+format for Vim scripts.
+
+If you want to use an old MS-DOS file in a modern environment, fixing line
+endings and dropping CTRL-Z, but keeping the <CR><NL> style <EOL>: >
+	setl ff=dos fixeol
+This is useful for many MS-Windows programs, they regularly expect the
+<CR><NL> line endings.
+
+If you want to drop the final <EOL> and add a final CTRL-Z (e.g. for an old
+system like CP/M): >
+	setl ff=dos nofixeol noeol eof
+
+If you want to preserve the fileformat exactly as-is, including any final
+<EOL> and final CTRL-Z: >
+	setl nofixeol
+
+==============================================================================
+3. The argument list				*argument-list* *arglist*
+
+If you give more than one file name when starting Vim, this list is remembered
+as the argument list.  You can jump to each file in this list.
+
+Do not confuse this with the buffer list, which you can see with the
+|:buffers| command.  The argument list was already present in Vi, the buffer
+list is new in Vim.  Every file name in the argument list will also be present
+in the buffer list (unless it was deleted with |:bdel| or |:bwipe|).  But it's
+common that names in the buffer list are not in the argument list.
+
+This subject is introduced in section |07.2| of the user manual.
+
+There is one global argument list, which is used for all windows by default.
+It is possible to create a new argument list local to a window, see
+|:arglocal|.
+
+You can use the argument list with the following commands, and with the
+expression functions |argc()| and |argv()|.  These all work on the argument
+list of the current window.
+
+							*:ar* *:arg* *:args*
+:ar[gs]			Print the argument list, with the current file in
+			square brackets.
+
+:ar[gs] [++opt] [+cmd] {arglist}			*:args_f*
+			Define {arglist} as the new argument list and edit
+			the first one.  This fails when changes have been made
+			and Vim does not want to |abandon| the current buffer.
+			Also see |++opt| and |+cmd|.
+
+:ar[gs]! [++opt] [+cmd] {arglist}			*:args_f!*
+			Define {arglist} as the new argument list and edit
+			the first one.  Discard any changes to the current
+			buffer.
+			Also see |++opt| and |+cmd|.
+
+:[count]arge[dit][!] [++opt] [+cmd] {name} ..		*:arge* *:argedit*
+			Add {name}s to the argument list and edit it.
+			When {name} already exists in the argument list, this
+			entry is edited.
+			This is like using |:argadd| and then |:edit|.
+			Spaces in filenames have to be escaped with "\".
+			[count] is used like with |:argadd|.
+			If the current file cannot be |abandon|ed {name}s will
+			still be added to the argument list, but won't be
+			edited. No check for duplicates is done.
+			Also see |++opt| and |+cmd|.
+
+:[count]arga[dd] {name} ..			*:arga* *:argadd* *E479*
+:[count]arga[dd]						*E1156*
+			Add the {name}s to the argument list.  When {name} is
+			omitted add the current buffer name to the argument
+			list.
+			If [count] is omitted, the {name}s are added just
+			after the current entry in the argument list.
+			Otherwise they are added after the [count]'th file.
+			If the argument list is "a b c", and "b" is the
+			current argument, then these commands result in:
+				command		new argument list ~
+				:argadd x	a b x c
+				:0argadd x	x a b c
+				:1argadd x	a x b c
+				:$argadd x	a b c x
+			And after the last one:
+				:+2argadd y	a b c x y
+			There is no check for duplicates, it is possible to
+			add a file to the argument list twice.  You can use
+			|:argdedupe| to fix it afterwards: >
+				:argadd *.txt | argdedupe
+<			The currently edited file is not changed.
+			Note: you can also use this method: >
+				:args ## x
+<			This will add the "x" item and sort the new list.
+
+:argded[upe]					*:argded* *:argdedupe*
+			Remove duplicate filenames from the argument list.
+			If your current file is a duplicate, your current file
+			will change to the original file index.
+
+:argd[elete] {pattern} ..		*:argd* *:argdelete* *E480* *E610*
+			Delete files from the argument list that match the
+			{pattern}s.  {pattern} is used like a file pattern,
+			see |file-pattern|.  "%" can be used to delete the
+			current entry.
+			This command keeps the currently edited file, also
+			when it's deleted from the argument list.
+			Example: >
+				:argdel *.obj
+
+:[range]argd[elete]	Delete the [range] files from the argument list.
+			Example: >
+				:10,$argdel
+<			Deletes arguments 10 and further, keeping 1-9. >
+				:$argd
+<			Deletes just the last one. >
+				:argd
+				:.argd
+<			Deletes the current argument. >
+				:%argd
+<			Removes all the files from the arglist.
+			When the last number in the range is too high, up to
+			the last argument is deleted.
+
+							*:argu* *:argument*
+:[count]argu[ment] [count] [++opt] [+cmd]
+			Edit file [count] in the argument list.  When [count]
+			is omitted the current entry is used.  This fails
+			when changes have been made and Vim does not want to
+			|abandon| the current buffer.
+			Also see |++opt| and |+cmd|.
+
+:[count]argu[ment]! [count] [++opt] [+cmd]
+			Edit file [count] in the argument list, discard any
+			changes to the current buffer.  When [count] is
+			omitted the current entry is used.
+			Also see |++opt| and |+cmd|.
+
+:[count]n[ext] [++opt] [+cmd]			*:n* *:ne* *:next* *E165* *E163*
+			Edit [count] next file.  This fails when changes have
+			been made and Vim does not want to |abandon| the
+			current buffer.  Also see |++opt| and |+cmd|.
+
+:[count]n[ext]! [++opt] [+cmd]
+			Edit [count] next file, discard any changes to the
+			buffer.  Also see |++opt| and |+cmd|.
+
+:n[ext] [++opt] [+cmd] {arglist}			*:next_f*
+			Same as |:args_f|.
+
+:n[ext]! [++opt] [+cmd] {arglist}
+			Same as |:args_f!|.
+
+:[count]N[ext] [count] [++opt] [+cmd]			*:Next* *:N* *E164*
+			Edit [count] previous file in argument list.  This
+			fails when changes have been made and Vim does not
+			want to |abandon| the current buffer.
+			Also see |++opt| and |+cmd|.
+
+:[count]N[ext]! [count] [++opt] [+cmd]
+			Edit [count] previous file in argument list.  Discard
+			any changes to the buffer.  Also see |++opt| and
+			|+cmd|.
+
+:[count]prev[ious] [count] [++opt] [+cmd]		*:prev* *:previous*
+			Same as :Next.  Also see |++opt| and |+cmd|.
+
+							*:rew* *:rewind*
+:rew[ind] [++opt] [+cmd]
+			Start editing the first file in the argument list.
+			This fails when changes have been made and Vim does
+			not want to |abandon| the current buffer.
+			Also see |++opt| and |+cmd|.
+
+:rew[ind]! [++opt] [+cmd]
+			Start editing the first file in the argument list.
+			Discard any changes to the buffer.  Also see |++opt|
+			and |+cmd|.
+
+							*:fir* *:first*
+:fir[st][!] [++opt] [+cmd]
+			Other name for ":rewind".
+
+							*:la* *:last*
+:la[st] [++opt] [+cmd]
+			Start editing the last file in the argument list.
+			This fails when changes have been made and Vim does
+			not want to |abandon| the current buffer.
+			Also see |++opt| and |+cmd|.
+
+:la[st]! [++opt] [+cmd]
+			Start editing the last file in the argument list.
+			Discard any changes to the buffer.  Also see |++opt|
+			and |+cmd|.
+
+							*:wn* *:wnext*
+:[count]wn[ext] [++opt]
+			Write current file and start editing the [count]
+			next file.  Also see |++opt| and |+cmd|.
+
+:[count]wn[ext] [++opt] {file}
+			Write current file to {file} and start editing the
+			[count] next file, unless {file} already exists and
+			the 'writeany' option is off.  Also see |++opt| and
+			|+cmd|.
+
+:[count]wn[ext]! [++opt] {file}
+			Write current file to {file} and start editing the
+			[count] next file.  Also see |++opt| and |+cmd|.
+
+:[count]wN[ext][!] [++opt] [file]		*:wN* *:wNext*
+:[count]wp[revious][!] [++opt] [file]		*:wp* *:wprevious*
+			Same as :wnext, but go to previous file instead of
+			next.
+
+The [count] in the commands above defaults to one.  For some commands it is
+possible to use two counts.  The last one (rightmost one) is used.
+
+If no [+cmd] argument is present, the cursor is positioned at the last known
+cursor position for the file.  If 'startofline' is set, the cursor will be
+positioned at the first non-blank in the line, otherwise the last know column
+is used.  If there is no last known cursor position the cursor will be in the
+first line (the last line in Ex mode).
+
+							*{arglist}*
+The wildcards in the argument list are expanded and the file names are sorted.
+Thus you can use the command "vim *.c" to edit all the C files.  From within
+Vim the command ":n *.c" does the same.
+
+White space is used to separate file names.  Put a backslash before a space or
+tab to include it in a file name.  E.g., to edit the single file "foo bar": >
+	:next foo\ bar
+
+On Unix and a few other systems you can also use backticks, for example: >
+	:next `find . -name \\*.c -print`
+The backslashes before the star are required to prevent "*.c" to be expanded
+by the shell before executing the find program.
+
+							*arglist-position*
+When there is an argument list you can see which file you are editing in the
+title of the window (if there is one and 'title' is on) and with the file
+message you get with the "CTRL-G" command.  You will see something like
+	(file 4 of 11)
+If 'shortmess' contains 'f' it will be
+	(4 of 11)
+If you are not really editing the file at the current position in the argument
+list it will be
+	(file (4) of 11)
+This means that you are position 4 in the argument list, but not editing the
+fourth file in the argument list.  This happens when you do ":e file".
+
+
+LOCAL ARGUMENT LIST
+
+							*:arglocal*
+:argl[ocal]		Make a local copy of the global argument list.
+			Doesn't start editing another file.
+
+:argl[ocal][!] [++opt] [+cmd] {arglist}
+			Define a new argument list, which is local to the
+			current window.  Works like |:args_f| otherwise.
+
+							*:argglobal*
+:argg[lobal]		Use the global argument list for the current window.
+			Doesn't start editing another file.
+
+:argg[lobal][!] [++opt] [+cmd] {arglist}
+			Use the global argument list for the current window.
+			Define a new global argument list like |:args_f|.
+			All windows using the global argument list will see
+			this new list.
+
+There can be several argument lists.  They can be shared between windows.
+When they are shared, changing the argument list in one window will also
+change it in the other window.
+
+When a window is split the new window inherits the argument list from the
+current window.  The two windows then share this list, until one of them uses
+|:arglocal| or |:argglobal| to use another argument list.
+
+
+USING THE ARGUMENT LIST
+
+						*:argdo*
+:[range]argdo[!] {cmd}	Execute {cmd} for each file in the argument list or
+			if [range] is specified only for arguments in that
+			range.  It works like doing this: >
+				:rewind
+				:{cmd}
+				:next
+				:{cmd}
+				etc.
+<			When the current file can't be |abandon|ed and the [!]
+			is not present, the command fails.
+			When an error is detected on one file, further files
+			in the argument list will not be visited.
+			The last file in the argument list (or where an error
+			occurred) becomes the current file.
+			{cmd} can contain '|' to concatenate several commands.
+			{cmd} must not change the argument list.
+			Note: While this command is executing, the Syntax
+			autocommand event is disabled by adding it to
+			'eventignore'.  This considerably speeds up editing
+			each file.
+			Also see |:windo|, |:tabdo|, |:bufdo|, |:cdo|, |:ldo|,
+			|:cfdo| and |:lfdo|
+
+Example: >
+	:args *.c
+	:argdo set ff=unix | update
+This sets the 'fileformat' option to "unix" and writes the file if it is now
+changed.  This is done for all *.c files.
+
+Example: >
+	:args *.[ch]
+	:argdo %s/\<my_foo\>/My_Foo/ge | update
+This changes the word "my_foo" to "My_Foo" in all *.c and *.h files.  The "e"
+flag is used for the ":substitute" command to avoid an error for files where
+"my_foo" isn't used.  ":update" writes the file only if changes were made.
+
+==============================================================================
+4. Writing					*writing* *save-file*
+
+Note: When the 'write' option is off, you are not able to write any file.
+
+							*:w* *:write*
+					*E502* *E503* *E504* *E505*
+					*E512* *E514* *E667* *E949*
+:w[rite] [++opt]	Write the whole buffer to the current file.  This is
+			the normal way to save changes to a file.  It fails
+			when the 'readonly' option is set or when there is
+			another reason why the file can't be written.
+			For ++opt see |++opt|, but only ++bin, ++nobin, ++ff
+			and ++enc are effective.
+
+:w[rite]! [++opt]	Like ":write", but forcefully write when 'readonly' is
+			set or there is another reason why writing was
+			refused.
+			Note: This may change the permission and ownership of
+			the file and break (symbolic) links.  Add the 'W' flag
+			to 'cpoptions' to avoid this.
+
+:[range]w[rite][!] [++opt]
+			Write the specified lines to the current file.  This
+			is unusual, because the file will not contain all
+			lines in the buffer.
+
+							*:w_f* *:write_f*
+:[range]w[rite] [++opt]	{file}
+			Write the specified lines to {file}, unless it
+			already exists and the 'writeany' option is off.
+
+							*:w!*
+:[range]w[rite]! [++opt] {file}
+			Write the specified lines to {file}.  Overwrite an
+			existing file.
+
+						*:w_a* *:write_a* *E494*
+:[range]w[rite][!] [++opt] >>
+			Append the specified lines to the current file.
+
+:[range]w[rite][!] [++opt] >> {file}
+			Append the specified lines to {file}.  '!' forces the
+			write even if file does not exist.
+
+							*:w_c* *:write_c*
+:[range]w[rite] [++opt] !{cmd}
+			Execute {cmd} with [range] lines as standard input
+			(note the space in front of the '!').  {cmd} is
+			executed like with ":!{cmd}", any '!' is replaced with
+			the previous command |:!|.
+
+The default [range] for the ":w" command is the whole buffer (1,$).  If you
+write the whole buffer, it is no longer considered changed.  When you
+write it to a different file with ":w somefile" it depends on the "+" flag in
+'cpoptions'.  When included, the write command will reset the 'modified' flag,
+even though the buffer itself may still be different from its file.
+
+If a file name is given with ":w" it becomes the alternate file.  This can be
+used, for example, when the write fails and you want to try again later with
+":w #".  This can be switched off by removing the 'A' flag from the
+'cpoptions' option.
+
+Note that the 'fsync' option matters here.  If it's set it may make writes
+slower (but safer).
+
+							*:sav* *:saveas*
+:sav[eas][!] [++opt] {file}
+			Save the current buffer under the name {file} and set
+			the filename of the current buffer to {file}.  The
+			previous name is used for the alternate file name.
+			The [!] is needed to overwrite an existing file.
+			When 'filetype' is empty filetype detection is done
+			with the new name, before the file is written.
+			When the write was successful 'readonly' is reset.
+
+							*:up* *:update*
+:[range]up[date][!] [++opt] [>>] [file]
+			Like ":write", but only write when the buffer has been
+			modified.
+
+
+WRITING WITH MULTIPLE BUFFERS				*buffer-write*
+
+							*:wa* *:wall*
+:wa[ll]			Write all changed buffers.  Buffers without a file
+			name cause an error message.  Buffers which are
+			readonly are not written.
+
+:wa[ll]!		Write all changed buffers, even the ones that are
+			readonly.  Buffers without a file name are not
+			written and cause an error message.
+
+
+Vim will warn you if you try to overwrite a file that has been changed
+elsewhere.  See |timestamp|.
+
+			    *backup* *E207* *E506* *E507* *E508* *E509* *E510*
+If you write to an existing file (but do not append) while the 'backup',
+'writebackup' or 'patchmode' option is on, a backup of the original file is
+made.  The file is either copied or renamed (see 'backupcopy').  After the
+file has been successfully written and when the 'writebackup' option is on and
+the 'backup' option is off, the backup file is deleted.  When the 'patchmode'
+option is on the backup file may be renamed.
+
+							*backup-table*
+'backup' 'writebackup'	action	~
+   off	     off	no backup made
+   off	     on		backup current file, deleted afterwards (default)
+   on	     off	delete old backup, backup current file
+   on	     on		delete old backup, backup current file
+
+When the 'backupskip' pattern matches with the name of the file which is
+written, no backup file is made.  The values of 'backup' and 'writebackup' are
+ignored then.
+
+When the 'backup' option is on, an old backup file (with the same name as the
+new backup file) will be deleted.  If 'backup' is not set, but 'writebackup'
+is set, an existing backup file will not be deleted.  The backup file that is
+made while the file is being written will have a different name.
+
+On some filesystems it's possible that in a crash you lose both the backup and
+the newly written file (it might be there but contain bogus data).  In that
+case try recovery, because the swap file is synced to disk and might still be
+there. |:recover|
+
+The directories given with the 'backupdir' option are used to put the backup
+file in.  (default: same directory as the written file).
+
+Whether the backup is a new file, which is a copy of the original file, or the
+original file renamed depends on the 'backupcopy' option.  See there for an
+explanation of when the copy is made and when the file is renamed.
+
+If the creation of a backup file fails, the write is not done.  If you want
+to write anyway add a '!' to the command.
+
+							*write-permissions*
+When writing a new file the permissions are read-write.  For unix the mask is
+0o666 with additionally umask applied.  When writing a file that was read Vim
+will preserve the permissions, but clear the s-bit.
+
+							*write-readonly*
+When the 'cpoptions' option contains 'W', Vim will refuse to overwrite a
+readonly file.  When 'W' is not present, ":w!" will overwrite a readonly file,
+if the system allows it (the directory must be writable).
+
+							*write-fail*
+If the writing of the new file fails, you have to be careful not to lose
+your changes AND the original file.  If there is no backup file and writing
+the new file failed, you have already lost the original file!  DON'T EXIT VIM
+UNTIL YOU WRITE OUT THE FILE!  If a backup was made, it is put back in place
+of the original file (if possible).  If you exit Vim, and lose the changes
+you made, the original file will mostly still be there.  If putting back the
+original file fails, there will be an error message telling you that you
+lost the original file.
+
+						*DOS-format-write*
+If the 'fileformat' is "dos", <CR><NL> is used for <EOL>.  This is default
+for Win32.  On other systems the message "[dos format]" is shown to remind you
+that an unusual <EOL> was used.
+						*Unix-format-write*
+If the 'fileformat' is "unix", <NL> is used for <EOL>.  On Win32 the message
+"[unix format]" is shown.
+						*Mac-format-write*
+If the 'fileformat' is "mac", <CR> is used for <EOL>.  On non-Mac systems the
+message "[mac format]" is shown.
+
+See also |file-formats| and the 'fileformat' and 'fileformats' options.
+
+						*ACL*
+ACL stands for Access Control List.  It is an advanced way to control access
+rights for a file.  It is used on new MS-Windows and Unix systems, but only
+when the filesystem supports it.
+   Vim attempts to preserve the ACL info when writing a file.  The backup file
+will get the ACL info of the original file.
+   The ACL info is also used to check if a file is read-only (when opening the
+file).
+
+					*xattr* *E1506* *E1508* *E1509*
+xattr stands for Extended Attributes.  It is an advanced way to save metadata
+alongside the file in the filesystem.  It depends on the actual filesystem
+being used and Vim supports it only on a Linux system.
+   Vim attempts to preserve the extended attribute info when writing a file.
+The backup file will get the extended attribute of the original file.
+
+						*read-only-share*
+When MS-Windows shares a drive on the network it can be marked as read-only.
+This means that even if the file read-only attribute is absent, and the ACL
+settings on NT network shared drives allow writing to the file, you can still
+not write to the file.  Vim on Win32 platforms will detect read-only network
+drives and will mark the file as read-only.  You will not be able to override
+it with |:write|.
+
+						*write-device*
+When the file name is actually a device name, Vim will not make a backup (that
+would be impossible).  You need to use "!", since the device already exists.
+Example for Unix: >
+	:w! /dev/lpt0
+and for MS-Windows: >
+	:w! lpt0
+For Unix a device is detected when the name doesn't refer to a normal file or
+a directory.  A fifo or named pipe also looks like a device to Vim.
+For MS-Windows the device is detected by its name:
+	AUX
+	CON
+	CLOCK$
+	NUL
+	PRN
+	COMn	n=1,2,3... etc
+	LPTn	n=1,2,3... etc
+The names can be in upper- or lowercase.
+
+==============================================================================
+5. Writing and quitting					*write-quit*
+
+							*:q* *:quit*
+:q[uit]			Quit the current window.  Quit Vim if this is the last
+			|edit-window|.  This fails when changes have been made
+			and Vim refuses to |abandon| the current buffer, and
+			when the last file in the argument list has not been
+			edited.
+			If there are other tab pages and quitting the last
+			window in the current tab page the current tab page is
+			closed |tab-page|.
+			Triggers the |QuitPre| autocommand event.
+			See |CTRL-W_q| for quitting another window.
+
+:conf[irm] q[uit]	Quit, but give prompt when changes have been made, or
+			the last file in the argument list has not been
+			edited.  See |:confirm| and 'confirm'.
+
+:q[uit]!		Quit without writing, also when the current buffer has
+			changes.  The buffer is unloaded, also when it has
+			'hidden' set.
+			If this is the last window and there is a modified
+			hidden buffer, the current buffer is abandoned and the
+			first changed hidden buffer becomes the current
+			buffer.
+			Use ":qall!" to exit always.
+
+:cq[uit]		Quit always, without writing, and return an error
+			code.  See |:cq|.  Used for Manx's QuickFix mode (see
+			|quickfix|).
+
+							*:wq*
+:wq [++opt]		Write the current file and close the window.  If this
+			was the last |edit-window| Vim quits.
+			Writing fails when the file is read-only or the buffer
+			does not have a name.  Quitting fails when the last
+			file in the argument list has not been edited.
+
+:wq! [++opt]		Write the current file and close the window.  If this
+			was the last |edit-window| Vim quits.  Writing fails
+			when the current buffer does not have a name.
+
+:wq [++opt] {file}	Write to {file} and close the window.  If this was the
+			last |edit-window| Vim quits.  Quitting fails when the
+			last file in the argument list has not been edited.
+
+:wq! [++opt] {file}	Write to {file} and close the current window.  Quit
+			Vim if this was the last |edit-window|.
+
+:[range]wq[!] [++opt] [file]
+			Same as above, but only write the lines in [range].
+
+							*:x* *:xit*
+:[range]x[it][!] [++opt] [file]
+			Like ":wq", but write only when changes have been
+			made.
+			When 'hidden' is set and there are more windows, the
+			current buffer becomes hidden, after writing the file.
+			This command is not supported in |Vim9| script,
+			because it is too easily confused with a variable
+			name.
+
+							*:exi* *:exit*
+:[range]exi[t][!] [++opt] [file]
+			Same as :xit.
+
+							*ZZ*
+ZZ			Write current file, if modified, and close the current
+			window (same as ":x").
+			If there are several windows for the current file,
+			only the current window is closed.
+
+							*ZQ*
+ZQ			Quit without checking for changes (same as ":q!").
+
+
+MULTIPLE WINDOWS AND BUFFERS				*window-exit*
+
+							*:qa* *:qall*
+:qa[ll]		Exit Vim, unless there are some buffers which have been
+		changed.  (Use ":bmod" to go to the next modified buffer).
+		When 'autowriteall' is set all changed buffers will be
+		written, like |:wqall|.
+
+:conf[irm] qa[ll]
+		Exit Vim.  Bring up a prompt when some buffers have been
+		changed.  See |:confirm|.
+
+:qa[ll]!	Exit Vim.  Any changes to buffers are lost.
+		Also see |:cquit|, it does the same but exits with a non-zero
+		value.
+
+							*:quita* *:quitall*
+:quita[ll][!]	Same as ":qall".
+
+:wqa[ll] [++opt]				*:wqa* *:wqall* *:xa* *:xall*
+:xa[ll]		Write all changed buffers and exit Vim.  If there are buffers
+		without a file name, which are readonly or which cannot be
+		written for another reason, Vim will not quit.
+
+:conf[irm] wqa[ll] [++opt]
+:conf[irm] xa[ll]
+		Write all changed buffers and exit Vim.  Bring up a prompt
+		when some buffers are readonly or cannot be written for
+		another reason.  See |:confirm|.
+
+:wqa[ll]! [++opt]
+:xa[ll]!	Write all changed buffers, even the ones that are readonly,
+		and exit Vim.  If there are buffers without a file name or
+		which cannot be written for another reason, or there is a
+		terminal with a running job, Vim will not quit.
+
+==============================================================================
+6. Dialogs						*edit-dialogs*
+
+							*:confirm* *:conf*
+:conf[irm] {command}	Execute {command}, and use a dialog when an
+			operation has to be confirmed.  Can be used on the
+			|:q|, |:qa| and |:w| commands (the latter to override
+			a read-only setting), and any other command that can
+			fail in such a way, such as |:only|, |:buffer|,
+			|:bdelete|, etc.
+
+Examples: >
+  :confirm w foo
+<	Will ask for confirmation when "foo" already exists. >
+  :confirm q
+<	Will ask for confirmation when there are changes. >
+  :confirm qa
+<	If any modified, unsaved buffers exist, you will be prompted to save
+	or abandon each one.  There are also choices to "save all" or "abandon
+	all".
+
+If you want to always use ":confirm", set the 'confirm' option.
+
+							*:browse* *:bro* *E338*
+:bro[wse] {command}	Open a file selection dialog for an argument to
+			{command}.  At present this works for |:e|, |:w|,
+			|:wall|, |:wq|, |:wqall|, |:x|, |:xall|, |:exit|,
+			|:view|, |:sview|, |:r|, |:saveas|, |:sp|, |:mkexrc|,
+			|:mkvimrc|, |:mksession|, |:mkview|, |:split|,
+			|:vsplit|, |:tabe|, |:tabnew|, |:cfile|, |:cgetfile|,
+			|:caddfile|, |:lfile|, |:lgetfile|, |:laddfile|,
+			|:diffsplit|, |:diffpatch|, |:open|, |:pedit|,
+			|:redir|, |:source|, |:update|, |:visual|, |:vsplit|,
+			and |:qall| if 'confirm' is set.
+			{only in Win32, Motif, GTK and Mac GUI, in
+			console `browse edit` works if the FileExplorer
+			autocommand group exists}
+			When ":browse" is not possible you get an error
+			message.  If the |+browse| feature is missing or the
+			{command} doesn't support browsing, the {command} is
+			executed without a dialog.
+			":browse set" works like |:options|.
+			See also |:oldfiles| for ":browse oldfiles".
+
+The syntax is best shown via some examples: >
+	:browse e $vim/foo
+<		Open the browser in the $vim/foo directory, and edit the
+		file chosen. >
+	:browse e
+<		Open the browser in the directory specified with 'browsedir',
+		and edit the file chosen. >
+	:browse w
+<		Open the browser in the directory of the current buffer,
+		with the current buffer filename as default, and save the
+		buffer under the filename chosen. >
+	:browse w C:/bar
+<		Open the browser in the C:/bar directory, with the current
+		buffer filename as default, and save the buffer under the
+		filename chosen.
+Also see the 'browsedir' option.
+For versions of Vim where browsing is not supported, the command is executed
+unmodified.
+
+							*browsefilter*
+For MS-Windows and GTK, you can modify the filters that are used in the browse
+dialog.  By setting the g:browsefilter or b:browsefilter variables, you can
+change the filters globally or locally to the buffer.  The variable is set to
+a string in the format "{filter label}\t{pattern};{pattern}\n" where {filter
+label} is the text that appears in the "Files of Type" comboBox, and {pattern}
+is the pattern which filters the filenames.  Several patterns can be given,
+separated by ';'.
+
+For Motif the same format is used, but only the very first pattern is actually
+used (Motif only offers one pattern, but you can edit it).
+
+For example, to have only Vim files in the dialog, you could use the following
+command: >
+
+     let g:browsefilter = "Vim Scripts\t*.vim\nVim Startup Files\t*vimrc\n"
+
+You can override the filter setting on a per-buffer basis by setting the
+b:browsefilter variable.  You would most likely set b:browsefilter in a
+filetype plugin, so that the browse dialog would contain entries related to
+the type of file you are currently editing.  Disadvantage: This makes it
+difficult to start editing a file of a different type.  To overcome this, you
+may want to add "All Files\t*.*\n" as the final filter, so that the user can
+still access any desired file.
+
+To avoid setting browsefilter when Vim does not actually support it, you can
+use has("browsefilter"): >
+
+	if has("browsefilter")
+	   let g:browsefilter = "whatever"
+	endif
+
+==============================================================================
+7. The current directory				*current-directory*
+
+You can use the |:cd|, |:tcd| and |:lcd| commands to change to another
+directory, so you will not have to type that directory name in front of the
+file names.  It also makes a difference for executing external commands, e.g.
+":!ls".
+
+Changing directory fails when the current buffer is modified, the '.' flag is
+present in 'cpoptions' and "!" is not used in the command.
+
+							*:cd* *E747* *E472*
+:cd[!]			On non-Unix systems when 'cdhome' is off: Print the
+			current directory name.
+			Otherwise: Change the current directory to the home
+			directory.  Clear any window-local directory.
+			Use |:pwd| to print the current directory on all
+			systems.
+
+:cd[!] {path}		Change the current directory to {path}.
+			If {path} is relative, it is searched for in the
+			directories listed in |'cdpath'|.
+			Clear any window-local directory.
+			Does not change the meaning of an already opened file,
+			because its full path name is remembered.  Files from
+			the |arglist| may change though!
+			On MS-Windows this also changes the active drive.
+			To change to the directory of the current file: >
+				:cd %:h
+<
+							*:cd-* *E186*
+:cd[!] -		Change to the previous current directory (before the
+			previous ":cd {path}" command).
+
+							*:chd* *:chdir*
+:chd[ir][!] [path]	Same as |:cd|.
+
+							*:tc* *:tcd*
+:tc[d][!] {path}	Like |:cd|, but only set the directory for the current
+			tab.  The current window will also use this directory.
+			The current directory is not changed for windows in
+			other tabs and for windows in the current tab that
+			have their own window-local directory.
+
+							*:tcd-*
+:tc[d][!] -		Change to the previous current directory, before the
+			last ":tcd {path}" command.
+
+							*:tch* *:tchdir*
+:tch[dir][!]		Same as |:tcd|.
+
+							*:lc* *:lcd*
+:lc[d][!] {path}	Like |:cd|, but only set the current directory when
+			the cursor is in the current window.  The current
+			directory for other windows is not changed, switching
+			to another window will stop using {path}.
+
+							*:lcd-*
+:lcd[!] -		Change to the previous current directory, before the
+			last ":lcd {path}" command.
+
+							*:lch* *:lchdir*
+:lch[dir][!]		Same as |:lcd|.
+
+							*:pw* *:pwd* *E187*
+:pw[d]			Print the current directory name.
+			Also see |getcwd()|.
+							*:pwd-verbose*
+			When 'verbose' is non-zero, |:pwd| will also display
+			what scope the current directory was set. Example: >
+
+				" Set by :cd
+				:verbose pwd
+				[global] /path/to/current
+
+				" Set by :lcd
+				:verbose pwd
+				[window] /path/to/current
+
+				" Set by :tcd
+				:verbose pwd
+				[tabpage] /path/to/current
+
+So long as no |:lcd| or |:tcd| command has been used, all windows share the
+same current directory.  Using a command to jump to another window doesn't
+change anything for the current directory.
+
+When a |:lcd| command has been used for a window, the specified directory
+becomes the current directory for that window.  Windows where the |:lcd|
+command has not been used stick to the global or tab-local current directory.
+When jumping to another window the current directory is changed to the last
+specified local current directory.  If none was specified, the global or
+tab-local current directory is used.  When creating a new window it inherits
+the local directory of the current window.
+
+When a |:tcd| command has been used for a tab page, the specified directory
+becomes the current directory for the current tab page and the current window.
+The current directory of other tab pages is not affected.  When jumping to
+another tab page, the current directory is changed to the last specified local
+directory for that tab page. If the current tab has no local current directory
+the global current directory is used.
+
+When a |:cd| command is used, the current window and tab page will lose the
+local current directory and will use the global current directory from now on.
+
+After using |:cd| the full path name will be used for reading and writing
+files.  On some networked file systems this may cause problems.  The result of
+using the full path name is that the file names currently in use will remain
+referring to the same file.  Example: If you have a file a:test and a
+directory a:vim the commands ":e test" ":cd vim" ":w" will overwrite the file
+a:test and not write a:vim/test.  But if you do ":w test" the file a:vim/test
+will be written, because you gave a new file name and did not refer to a
+filename before the ":cd".
+
+==============================================================================
+8. Editing binary files					*edit-binary*
+
+Although Vim was made to edit text files, it is possible to edit binary
+files.  The |-b| Vim argument (b for binary) makes Vim do file I/O in binary
+mode, and sets some options for editing binary files ('binary' on, 'textwidth'
+to 0, 'modeline' off, 'expandtab' off).  Setting the 'binary' option has the
+same effect.  Don't forget to do this before reading the file.
+
+There are a few things to remember when editing binary files:
+- When editing executable files the number of bytes must not change.
+  Use only the "R" or "r" command to change text.  Do not delete characters
+  with "x" or by backspacing.
+- Set the 'textwidth' option to 0.  Otherwise lines will unexpectedly be
+  split in two.
+- When there are not many <EOL>s, the lines will become very long.  If you
+  want to edit a line that does not fit on the screen reset the 'wrap' option.
+  Horizontal scrolling is used then.  If a line becomes too long (more than
+  about 32767 bytes on the Amiga, much more on 32-bit and 64-bit systems, see
+  |limits|) you cannot edit that line.  The line will be split when reading
+  the file.  It is also possible that you get an "out of memory" error when
+  reading the file.
+- Make sure the 'binary' option is set BEFORE loading the
+  file.  Otherwise both <CR><NL> and <NL> are considered to end a line
+  and when the file is written the <NL> will be replaced with <CR><NL>.
+- <Nul> characters are shown on the screen as ^@.  You can enter them with
+  "CTRL-V CTRL-@" or "CTRL-V 000"
+- To insert a <NL> character in the file split a line.  When writing the
+  buffer to a file a <NL> will be written for the <EOL>.
+- Vim normally appends an <EOL> at the end of the file if there is none.
+  Setting the 'binary' option prevents this.  If you want to add the final
+  <EOL>, set the 'endofline' option.  You can also read the value of this
+  option to see if there was an <EOL> for the last line (you cannot see this
+  in the text).
+
+==============================================================================
+9. Encryption						*encryption*
+
+Vim is able to write files encrypted, and read them back.  The encrypted text
+cannot be read without the right key.
+{only available when compiled with the |+cryptv| feature}  *E833*
+
+The text in the swap file and the undo file is also encrypted.  *E843*
+However, this is done block-by-block and may reduce the time needed to crack a
+password.  You can disable the swap file, but then a crash will cause you to
+lose your work.  The undo file can be disabled without too much disadvantage. >
+	:set noundofile
+	:noswapfile edit secrets
+
+Note: The text in memory is not encrypted.  A system administrator may be able
+to see your text while you are editing it.  When filtering text with
+":!filter" or using ":w !command" the text is also not encrypted, this may
+reveal it to others.  The 'viminfo' file is not encrypted.
+
+You could do this to edit very secret text: >
+	:set noundofile viminfo=
+	:noswapfile edit secrets.txt
+Keep in mind that without a swap file you risk losing your work in the event
+of a crash or a power failure.
+
+WARNING: If you make a typo when entering the key and then write the file and
+exit, the text will be lost!
+
+The normal way to work with encryption, is to use the ":X" command, which will
+ask you to enter a key.  A following write command will use that key to
+encrypt the file.  If you later edit the same file, Vim will ask you to enter
+a key.  If you type the same key as that was used for writing, the text will
+be readable again.  If you use a wrong key, it will be a mess.
+
+							*:X*
+:X	Prompt for an encryption key.  The typing is done without showing the
+	actual text, so that someone looking at the display won't see it.
+	The typed key is stored in the 'key' option, which is used to encrypt
+	the file when it is written.
+	The file will remain unchanged until you write it.  Note that commands
+	such as `:xit` and `ZZ` will NOT write the file unless there are other
+	changes.
+	See also |-x|.
+
+The value of the 'key' options is used when text is written.  When the option
+is not empty, the written file will be encrypted, using the value as the
+encryption key.  A magic number is prepended, so that Vim can recognize that
+the file is encrypted.
+
+To disable the encryption, reset the 'key' option to an empty value: >
+	:set key=
+
+You can use the 'cryptmethod' option to select the type of encryption, use one
+of these: >
+	:setlocal cm=zip          " weak method, backwards compatible
+	:setlocal cm=blowfish     " method with flaws, do not use
+	:setlocal cm=blowfish2    " medium strong method
+	:setlocal cm=xchacha20v2  " medium strong method using libsodium
+
+Do this before writing the file.  When reading an encrypted file it will be
+set automatically to the method used when that file was written.  You can
+change 'cryptmethod' before writing that file to change the method.
+
+To set the default method, used for new files, use this in your |vimrc|
+file: >
+	set cm=blowfish2
+Using "blowfish2" is highly recommended.  Only use another method if you
+must use an older Vim version that does not support it.
+
+The message given for reading and writing a file will show "[crypted]" when
+using zip, "[blowfish]" when using blowfish, etc.
+
+When writing an undo file, the same key and method will be used for the text
+in the undo file. |persistent-undo|.
+
+To test for blowfish support you can use these conditions: >
+	has('crypt-blowfish')
+	has('crypt-blowfish2')
+This works since Vim 7.4.1099 while blowfish support was added earlier.
+Thus the condition failing doesn't mean blowfish is not supported. You can
+test for blowfish with: >
+	v:version >= 703
+And for blowfish2 with: >
+	v:version > 704 || (v:version == 704 && has('patch401'))
+If you are sure Vim includes patch 7.4.237 a simpler check is: >
+	has('patch-7.4.401')
+<
+						*E817* *E818* *E819* *E820*
+When encryption does not work properly, you would be able to write your text
+to a file and never be able to read it back.  Therefore a test is performed to
+check if the encryption works as expected.  If you get one of these errors
+don't write the file encrypted!  You need to rebuild the Vim binary to fix
+this.
+
+*E831* This is an internal error, "cannot happen".  If you can reproduce it,
+please report to the developers.
+
+When reading a file that has been encrypted and the 'key' option is not empty,
+it will be used for decryption.  If the value is empty, you will be prompted
+to enter the key.  If you don't enter a key, or you enter the wrong key, the
+file is edited without being decrypted.  There is no warning about using the
+wrong key (this makes brute force methods to find the key more difficult).
+
+If want to start reading a file that uses a different key, set the 'key'
+option to an empty string, so that Vim will prompt for a new one.  Don't use
+the ":set" command to enter the value, other people can read the command over
+your shoulder.
+
+Since the value of the 'key' option is supposed to be a secret, its value can
+never be viewed.  You should not set this option in a vimrc file.
+
+An encrypted file can be recognized by the "file" command, if you add these
+lines to "/etc/magic", "/usr/share/misc/magic" or wherever your system has the
+"magic" file: >
+     0	string	VimCrypt~	Vim encrypted file
+     >9	string	01	- "zip" cryptmethod
+     >9	string	02	- "blowfish" cryptmethod
+     >9	string	03	- "blowfish2" cryptmethod
+
+Notes:
+- Encryption is not possible when doing conversion with 'charconvert'.
+- Text you copy or delete goes to the numbered registers.  The registers can
+  be saved in the .viminfo file, where they could be read.  Change your
+  'viminfo' option to be safe.
+- Someone can type commands in Vim when you walk away for a moment, he should
+  not be able to get the key.
+- If you make a typing mistake when entering the key, you might not be able to
+  get your text back!
+- If you type the key with a ":set key=value" command, it can be kept in the
+  history, showing the 'key' value in a viminfo file.
+- There is never 100% safety.  The encryption in Vim has not been tested for
+  robustness.
+- The algorithm used for 'cryptmethod' "zip" is breakable.  A 4 character key
+  in about one hour, a 6 character key in one day (on a Pentium 133 PC).  This
+  requires that you know some text that must appear in the file.  An expert
+  can break it for any key.  When the text has been decrypted, this also means
+  that the key can be revealed, and other files encrypted with the same key
+  can be decrypted.
+- Pkzip uses the same encryption as 'cryptmethod' "zip", and US Govt has no
+  objection to its export.  Pkzip's public file APPNOTE.TXT describes this
+  algorithm in detail.
+- The implementation of 'cryptmethod' "blowfish" has a flaw.  It is possible
+  to crack the first 64 bytes of a file and in some circumstances more of the
+  file. Use of it is not recommended, but it's still the strongest method
+  supported by Vim 7.3 and 7.4.  The "zip" method is even weaker.
+- Vim originates from the Netherlands.  That is where the sources come from.
+  Thus the encryption code is not exported from the USA.
+
+==============================================================================
+10. Timestamps					*timestamp* *timestamps*
+
+Vim remembers the modification timestamp, mode and size of a file when you
+begin editing it.  This is used to avoid that you have two different versions
+of the same file (without you knowing this).
+
+After a shell command is run (|:!cmd| |suspend| |:read!| |K|) timestamps,
+file modes and file sizes are compared for all buffers in a window.   Vim will
+run any associated |FileChangedShell| autocommands or display a warning for
+any files that have changed.  In the GUI this happens when Vim regains input
+focus.
+
+							*E321* *E462*
+If you want to automatically reload a file when it has been changed outside of
+Vim, set the 'autoread' option.  This doesn't work at the moment you write the
+file though, only when the file wasn't changed inside of Vim.
+							*ignore-timestamp*
+If you do not want to be asked or automatically reload the file, you can use
+this: >
+	set buftype=nofile
+
+Or, when starting gvim from a shell: >
+	gvim file.log -c "set buftype=nofile"
+
+Note that if a FileChangedShell autocommand is defined you will not get a
+warning message or prompt.  The autocommand is expected to handle this.
+
+There is no warning for a directory (e.g., with |netrw-browse|).  But you do
+get warned if you started editing a new file and it was created as a directory
+later.
+
+When Vim notices the timestamp of a file has changed, and the file is being
+edited in a buffer but has not changed, Vim checks if the contents of the file
+is equal.  This is done by reading the file again (into a hidden buffer, which
+is immediately deleted again) and comparing the text.  If the text is equal,
+you will get no warning.
+
+If you don't get warned often enough you can use the following command.
+
+							*:checkt* *:checktime*
+:checkt[ime]		Check if any buffers were changed outside of Vim.
+			This checks and warns you if you would end up with two
+			versions of a file.
+			If this is called from an autocommand, a ":global"
+			command or is not typed the actual check is postponed
+			until a moment the side effects (reloading the file)
+			would be harmless.
+			Each loaded buffer is checked for its associated file
+			being changed.  If the file was changed Vim will take
+			action.  If there are no changes in the buffer and
+			'autoread' is set, the buffer is reloaded.  Otherwise,
+			you are offered the choice of reloading the file.  If
+			the file was deleted you get an error message.
+			If the file previously didn't exist you get a warning
+			if it exists now.
+			Once a file has been checked the timestamp is reset,
+			you will not be warned again.
+			Syntax highlighting, marks, diff status,
+			'fileencoding', 'fileformat' and 'binary' options
+			are not changed.  See |v:fcs_choice| to reload these
+			too (for example, if a code formatting tools has
+			changed the file).
+
+:[N]checkt[ime] {filename}
+:[N]checkt[ime] [N]
+			Check the timestamp of a specific buffer.  The buffer
+			may be specified by name, number or with a pattern.
+
+
+							*E813* *E814*
+Vim will reload the buffer if you chose to.  If a window is visible that
+contains this buffer, the reloading will happen in the context of this window.
+Otherwise a special window is used, so that most autocommands will work.  You
+can't close this window.  A few other restrictions apply.  Best is to make
+sure nothing happens outside of the current buffer.  E.g., setting
+window-local options may end up in the wrong window.  Splitting the window,
+doing something there and closing it should be OK (if there are no side
+effects from other autocommands).  Closing unrelated windows and buffers will
+get you into trouble.
+
+Before writing a file the timestamp is checked.  If it has changed, Vim will
+ask if you really want to overwrite the file:
+
+	WARNING: The file has been changed since reading it!!!
+	Do you really want to write to it (y/n)?
+
+If you hit 'y' Vim will continue writing the file.  If you hit 'n' the write is
+aborted.  If you used ":wq" or "ZZ" Vim will not exit, you will get another
+chance to write the file.
+
+The message would normally mean that somebody has written to the file after
+the edit session started.  This could be another person, in which case you
+probably want to check if your changes to the file and the changes from the
+other person should be merged.  Write the file under another name and check for
+differences (the "diff" program can be used for this).
+
+It is also possible that you modified the file yourself, from another edit
+session or with another command (e.g., a filter command).  Then you will know
+which version of the file you want to keep.
+
+The accuracy of the time check depends on the filesystem.  On Unix it is
+usually sub-second.  With old file systems and on MS-Windows it is normally one
+second.  Use `has('nanotime')` to check if sub-second time stamp checks are
+available.
+
+There is one situation where you get the message while there is nothing wrong:
+On a Win32 system on the day daylight saving time starts.  There is something
+in the Win32 libraries that confuses Vim about the hour time difference.  The
+problem goes away the next day.

+11. File Searching					*file-searching*
+
+The file searching is currently used for the 'path', 'cdpath' and 'tags'
+options, for |finddir()| and |findfile()|.  Other commands use |wildcards|
+which is slightly different.
+
+There are three different types of searching:
+
+1) Downward search:					*starstar*
+   Downward search uses the wildcards '*', '**' and possibly others
+   supported by your operating system.  '*' and '**' are handled inside Vim,
+   so they work on all operating systems.  Note that "**" only acts as a
+   special wildcard when it is at the start of a name.
+
+   The usage of '*' is quite simple: It matches 0 or more characters.  In a
+   search pattern this would be ".*".  Note that the "." is not used for file
+   searching.
+
+   '**' is more sophisticated:
+      - It ONLY matches directories.
+      - It matches up to 30 directories deep by default, so you can use it to
+	search an entire directory tree
+      - The maximum number of levels matched can be given by appending a number
+	to '**'.
+	Thus '/usr/**2' can match: >
+		/usr
+		/usr/include
+		/usr/include/sys
+		/usr/include/g++
+		/usr/lib
+		/usr/lib/X11
+		....
+<	It does NOT match '/usr/include/g++/std' as this would be three
+	levels.
+	The allowed number range is 0 ('**0' is removed) to 100
+	If the given number is smaller than 0 it defaults to 30, if it's
+	bigger than 100 then 100 is used.  The system also has a limit on the
+	path length, usually 256 or 1024 bytes.
+      - '**' can only be at the end of the path or be followed by a path
+	separator or by a number and a path separator.
+
+   You can combine '*' and '**' in any order: >
+	/usr/**/sys/*
+	/usr/*tory/sys/**
+	/usr/**2/sys/*
+
+2) Upward search:
+   Here you can give a directory and then search the directory tree upward for
+   a file.  You could give stop-directories to limit the upward search.  The
+   stop-directories are appended to the path (for the 'path' option) or to
+   the filename (for the 'tags' option) with a ';'.  If you want several
+   stop-directories separate them with ';'.  If you want no stop-directory
+   ("search upward till the root directory) just use ';'. >
+	/usr/include/sys;/usr
+<   will search in: >
+	   /usr/include/sys
+	   /usr/include
+	   /usr
+<
+   If you use a relative path the upward search is started in Vim's current
+   directory or in the directory of the current file (if the relative path
+   starts with './' and 'd' is not included in 'cpoptions').
+
+   If Vim's current path is /u/user_x/work/release and you do >
+	:set path=include;/u/user_x
+<  and then search for a file with |gf| the file is searched in: >
+	/u/user_x/work/release/include
+	/u/user_x/work/include
+	/u/user_x/include
+
+<   Note: If your 'path' setting includes a non-existing directory, Vim will
+   skip the non-existing directory, and also does not search in the parent of
+   the non-existing directory if upwards searching is used.
+
+3) Combined up/downward search:
+   If Vim's current path is /u/user_x/work/release and you do >
+	set path=**;/u/user_x
+<  and then search for a file with |gf| the file is searched in: >
+	/u/user_x/work/release/**
+	/u/user_x/work/**
+	/u/user_x/**
+<
+   BE CAREFUL!  This might consume a lot of time, as the search of
+   '/u/user_x/**' includes '/u/user_x/work/**' and
+   '/u/user_x/work/release/**'.  So '/u/user_x/work/release/**' is searched
+   three times and '/u/user_x/work/**' is searched twice.
+
+   In the above example you might want to set path to: >
+	:set path=**,/u/user_x/**
+<  This searches:
+	/u/user_x/work/release/** ~
+	/u/user_x/** ~
+   This searches the same directories, but in a different order.
+
+   Note that completion for ":find", ":sfind", and ":tabfind" commands do not
+   currently work with 'path' items that contain a URL or use the double star
+   with depth limiter (/usr/**2) or upward search (;) notations.
