+.\"NODE "Overview"
+.SH "Overview"
+The screen of Midnight Commander is divided into four parts.
+Almost all of the screen space is taken up by two directory panels.
+By default, the second line from the bottom of the screen is the
+shell command line, and the bottom line shows the function key labels.
+The topmost line is the
+.\"LINK2"
+menu bar line\&.
+.\"Menu Bar"
+The menu bar line may not be visible, but appears if you click the
+topmost line with the mouse or press the F9 key.
+.PP
+Midnight Commander provides a view of two directories at the same
+time. One of the panels is the current panel (a selection bar is in
+the current panel). Almost all operations take place on the current
+panel. Some file operations like Rename and Copy by default use the
+directory of the unselected panel as a destination (don't worry, they
+always ask you for confirmation first). For more information, see the
+sections on the
+.\"LINK2"
+Directory Panels\&,
+.\"Directory Panels"
+the
+.\"LINK2"
+Left and Right Menus
+.\"Left and Right Menus"
+and the
+.\"LINK2"
+File Menu\&.
+.\"File Menu"
+.PP
+You can execute system commands from Midnight Commander by simply
+typing them. Everything you type will appear on the shell command line,
+and when you press Enter, Midnight Commander will execute the
+command line you typed; read the
+.\"LINK2"
+Shell Command Line
+.\"Shell Command Line"
+and
+.\"LINK2"
+Input Line Keys
+.\"Input Line Keys"
+sections to learn more about the command line.
+.\"NODE "Mouse Support"
+.SH "Mouse Support"
+Midnight Commander comes with mouse support. It is activated
+whenever you are running on an
+.B xterm(1)
+terminal (it even works if you take a telnet, ssh or rlogin connection to
+another machine from the xterm) or if you are running on a Linux
+console and have the
+.B gpm
+mouse server running.
+.PP
+When you left click on a file in the directory panels, that file is
+selected; if you click with the right button, the file is marked (or
+unmarked, depending on the previous state).
+.PP
+Double\-clicking on a file will try to execute the command if it is
+an executable program; and if the
+.\"LINK2"
+extension file
+.\"Edit Extension File"
+has a program specified for the file's extension, the specified
+program is executed.
+.PP
+Also, it is possible to execute the commands assigned to the function
+key labels by clicking on them.
+.PP
+The default auto repeat rate for the mouse buttons is 400
+milliseconds. This may be changed to other values by editing the
+.\"LINK2"
+\&~/.config/mc/ini
+.\"Save Setup"
+file and changing the
+.I mouse_repeat_rate
+parameter.
+.PP
+If you are running Midnight Commander with the mouse support, you
+can get the default mouse behavior (cutting and pasting text) by holding
+down the Shift key.
+.SH ""
+.\"NODE "Keys"
+.SH "Keys"
+Some commands in Midnight Commander involve the use of the
+.I Control
+(sometimes labeled CTRL or CTL) and the
+.I Meta
+(sometimes labeled ALT or even Compose) keys. In this manual we will
+use the following abbreviations:
+.TP
+.B C\-<chr>
+means hold the Control key while typing the character <chr>.
+Thus C\-f would be: hold the Control key and type f.
+.TP
+.B Alt\-<chr>
+means hold the Meta or Alt key down while typing <chr>.
+If there is no Meta or Alt key, type
+.IR Esc ,
+release it, then type the character <chr>.
+.TP
+.B S\-<chr>
+means hold the Shift key down while typing <chr>.
+.PP
+All input lines in Midnight Commander use an approximation to
+the GNU Emacs editor's key bindings (default).
+.PP
+You may redefine key bindings. See
+.\"LINK2"
+.I redefine hotkey bindings
+.\"Keys_redefine"
+.PP
+for more info. All other key bindings (described in this manual) are relative
+to default behavior.
+
+.PP
+There are many sections which tell about the keys. The following are
+the most important.
+.PP
+The
+.\"LINK2"
+File Menu
+.\"File Menu"
+section documents the keyboard shortcuts for the commands appearing in
+the File menu. This section includes the function keys. Most of these
+commands perform some action, usually on the selected file or the
+tagged files.
+.PP
+The
+.\"LINK2"
+Directory Panels
+.\"Directory Panels"
+section documents the keys which select a file or tag files as a
+target for a later action (the action is usually one from the file
+menu).
+.PP
+The
+.\"LINK2"
+Shell Command Line
+.\"Shell Command Line"
+section list the keys which are used for entering and editing command
+lines. Most of these copy file names and such from the directory
+panels to the command line (to avoid excessive typing) or access the
+command line history.
+.PP
+.\"LINK2"
+Input Line Keys
+.\"Input Line Keys"
+are used for editing input lines. This means both the command line and
+the input lines in the query dialogs.
+
+.\"NODE "  Keys_redefine"
+.SH "  Redefine hotkey bindings"
+Hotkey bindings may be read from external file (keymap\-file).
+Initially, Midnight Commander creates key bindings using keymap defined
+in the source code. Then, two files
+.B %pkgdatadir%/mc.keymap
+and
+.B %sysconfdir%/mc/mc.keymap
+are loaded always, sequentially reassigned key bindings defined earlier.
+User\-defined keymap\-file is searched on the following algorithm (to the first one found):
+.IP
+.br
+1) command line option
+.B \-K <keymap>
+or
+.B \-\-keymap=<keymap>
+.br
+2) Environment variable
+.B MC_KEYMAP
+.br
+3) Parameter
+.B keymap
+in section
+.B [Midnight\-Commander]
+of config file.
+.br
+4) File
+.B ~/.config/mc/mc.keymap
+.br
+.PP
+Command line option, environment variable and parameter in config file may
+contain the absolute path to the keymap\-file (with the extension \.keymap
+or without it). Search of keymap\-file will occur in (to the first one found):
+.IP
+.br
+1)
+.B ~/.config/mc
+.br
+2)
+.B %sysconfdir%/mc/
+.br
+3)
+.B %pkgdatadir%/
+
+.\"NODE "  Miscellaneous Keys"
+.SH "  Miscellaneous Keys"
+Here are some keys which don't fall into any of the other categories:
+.TP
+.B Enter
+if there is some text in the command line (the one at the bottom of
+the panels), then that command is executed. If there is no text in the
+command line then if the selection bar is over a directory the
+Midnight Commander does a
+.B chdir(2)
+to the selected directory and reloads the information on the panel;
+if the selection is an executable file then it is executed. Finally,
+if the extension of the selected file name matches one of the
+extensions in the
+.\"LINK2"
+extensions file
+.\"Edit Extension File"
+then the corresponding command is executed.
+.TP
+.B C\-l
+repaint all the information in Midnight Commander.
+.TP
+.B C\-x c
+run the
+.\"LINK2"
+Chmod
+.\"Chmod"
+command on a file or on the tagged files.
+.TP
+.B C\-x o
+run the
+.\"LINK2"
+Chown
+.\"Chown"
+command on the current file or on the tagged files.
+.TP
+.B C\-x l
+run the hard link command.
+.TP
+.B C\-x s
+run the absolute symbolic link command.
+.TP
+.B C\-x v
+run the relative symbolic link command. See the
+.\"LINK2"
+File Menu
+.\"File Menu"
+section for more information about symbolic links.
+.TP
+.B C\-x i
+set the other panel display mode to information.
+.TP
+.B C\-x q
+set the other panel display mode to quick view.
+.TP
+.B C\-x !

+.\"External panelize"
+command.
+.TP
+.B C\-x h
+run the
+.\"LINK2"
+add directory to hotlist
+.\"Hotlist"
+command.
+.TP
+.B Alt\-!
+executes the Filtered view command, described in the
+.\"LINK2"

+.\"Internal File Viewer"
+.TP
+.B Alt\-?
+executes the
+.\"LINK2"
+Find file
+.\"Find File"
+command.
+.TP
+.B Alt\-c
+pops up the
+.\"LINK2"
+quick cd
+.\"Quick cd"
+dialog.
+.TP
+.B C\-o
+when the program is being run in the Linux or FreeBSD console or under
+an xterm, it will show you the output of the previous command.  When ran
+on the Linux console, Midnight Commander uses an external program
+(cons.saver) to handle saving and restoring of information on the
+screen.
+.PP
+When the subshell support is compiled in, you can type C\-o at any time
+and you will be taken back to Midnight Commander's main screen, to
+return to your application just type C\-o.  If you have an application
+suspended by using this trick, you won't be able to execute other
+programs from Midnight Commander until you terminate the suspended
+application.
+.\"NODE "  Directory Panels"
+.SH "  Directory Panels"
+This section lists the keys which operate on the directory panels. If
+you want to know how to change the appearance of the panels take a
+look at the section on
+.\"LINK2"
+Left and Right Menus\&.
+.\"Left and Right Menus"
+.TP
+.B Tab, C\-i
+change the current panel. The old other panel becomes the new current
+panel and the old current panel becomes the new other panel. The
+selection bar moves from the old current panel to the new current
+panel.
+.TP
+.B Insert, C\-t
+to tag files you may use the Insert key (the kich1 terminfo sequence).
+To untag files, just retag a tagged file.
+.TP
+.B Alt\-e
+to change charset of panel you may use Alt\-e (M\-e).
+Recoding is made from selected codepage into system codepage. To
+cancel the recoding, select "No translation" in the dialog of encodings.
+.TP
+.B Alt\-g, Alt\-r, Alt\-j
+used to select the top file in a panel, the middle file and the bottom one,
+respectively.
+.TP
+.B Alt\-t
+toggle the current display listing to show the next display listing
+format.
+With this it is possible to quickly switch to brief listing, long
+listing, user defined listing format, and back to the default.
+.TP
+.B C\-\\\\ (control\-backslash)
+show the
+.\"LINK2"
+directory hotlist
+.\"Hotlist"
+and change to the selected directory.
+.TP
+.B + \ (plus)
+this is used to select (tag) a group of files. Midnight Commander
+will prompt for a selection options. When
+.I Files only
+checkbox is on, only files will be selected.  If
+.I Files only
+is off, as files as directories will be selected.
+When
+.I Shell Patterns
+checkbox is on, the regular expression is much like the filename globbing
+in the shell (* standing for zero or more characters and ? standing
+for one character). If
+.I Shell Patterns
+is off, then the tagging of files is done with normal regular
+expressions (see ed (1)). When
+.I Case sensitive
+checkbox is on, the selection will be case sensitive characters.
+If
+.I Case sensitive
+is off, the case will be ignored.
+.TP
+.B \\\\ (backslash)
+use the "\\" key to unselect a group of files. This is the opposite of
+the Plus key.
+.TP
+.B up\-key, C\-p
+move the selection bar to the previous entry in the panel.
+.TP
+.B down\-key, C\-n
+move the selection bar to the next entry in the panel.
+.TP

+.TP
+.B prev\-page, Alt\-v
+move the selection bar one page up.
+.TP
+.B Alt\-o
+If the currently selected file is a directory, load that directory on
+the other panel and moves the selection to the next file. If the
+currently selected file is not a directory, load the parent directory
+on the other panel and moves the selection to the next file.
+.TP
+.B Alt\-i
+make the current directory of the current panel also the current
+directory of the other panel.  Put the other panel to the listing mode
+if needed.  If the current panel is panelized, the other panel doesn't
+become panelized.
+.TP
+.B C\-PageUp, C\-PageDown
+only when supported by the terminal: change to ".." and to the currently
+selected directory respectively.
+.TP
+.B Alt\-y
+moves to the previous directory in the history, equivalent to clicking
+the

+.\"NODE "  Quick search"
+.SH "  Quick search"
+The Quick search mode allows you to perform fast file search in file panel.
+Press
+.I C\-s
+or
+.I Alt\-s
+to start a filename search in the directory listing.
+.P
+When the search is active, the user input will be added to the search string
+instead of the command line. If the
+.I Show mini\-status
+option is enabled the search string is shown on the mini\-status
+line. When typing, the selection bar will move to the next file
+starting with the typed letters. The
+.I Backspace
+or
+.I DEL
+keys can be used to correct typing mistakes. If C\-s is pressed
+again, the next match is searched for.
+.P
+If quick search is started with double pressing of C\-s, the previous quick
+search pattern will be used for current search.
+.P
+Besides the filename characters, you can also use wildcard
+characters '*' and '?'.
+.\"NODE "  Shell Command Line"

+The listing mode view is used to display a listing of files, there are
+four different listing formats available:
+.BR Full ,
+.BR Brief ,
+.B Long
+and
+.BR User .
+The full directory view shows the file name, the size of the file and
+the modification time.
+.PP
+The brief view shows only the file name and it has from 1 up to 9 columns
+(therefore showing more files unlike other views). The long view
+is similar to the output of
+.B "ls \-l"
+command. The long view takes the whole screen width.
+.PP
+If you choose the "User" display format, then you have to specify
+the display format.
+.PP
+The user display format must start with a panel size specifier.  This
+may be "half" or "full", and they specify a half screen panel and a
+full screen panel respectively.
+.PP
+After the panel size, you may specify how many listings to fit in the
+panel, side\-by\-side (in other words: how many times to repeat the
+fields horizontally). This defaults to 1. You may change this by adding a
+number from 1 to 9 to the format string.
+.PP
+After this you add the name of the fields with an optional size
+specifier.  This are the available fields you may display:

+an octal value with the current permission bits of the file.
+.TP
+.B nlink
+the number of links to the file.
+.TP
+.B ngid

+.TP
+.B nuid
+the UID (numeric).
+.TP
+.B owner
+the owner of the file.
+.TP
+.B group

+.PP
+Also you can use following keywords to define the panel layout:
+.TP
+.B space
+a space in the display format.
+.TP
+.B |
+add a vertical line to the display format.
+.PP
+To force one field to a fixed size (a size specifier), you just add
+.B :
+followed by the number of characters you want the field to have.  If the
+number is followed by the symbol
+.BR + ,
+then the size specifies the minimal field size \- if the program finds
+out that there is more space on the screen, it will then expand that
+field.
+.PP
+For example, the
+.B Full
+display corresponds to this format:
+.PP
+half type name | size | mtime
+.PP
+And the
+.B Long
+display corresponds to this format:
+.PP
+full perm space nlink space owner space group space size space mtime
+space name
+.PP
+This is a nice user display format:
+.PP
+half name | size:7 | type mode:3
+.PP
+Panels may also be set to the following modes:
+.TP
+.B "Info"
+The info view display information related to the currently
+selected file and if possible information about the current file
+system.
+.TP
+.B "Tree"
+The tree view is quite similar to the
+.\"LINK2"
+directory tree
+.\"Directory Tree"
+feature. See the section about it for more information.
+.TP
+.B "Quick View"
+In this mode, the panel will switch to a reduced
+.\"LINK2"
+viewer
+.\"Internal File Viewer"
+that displays the contents of the currently selected file, if you
+select the panel (with the tab key or the mouse), you will have access
+to the usual viewer commands.
+.\"NODE "    Sort Order..."
+.SH "    Sort Order..."
+The eight sort orders are by name, by extension, by modification time,
+by access time, and by inode information modification time, by size,
+by inode and unsorted.  In the Sort order dialog box you can choose
+the sort order and you may also specify if you want to sort in reverse
+order by checking the reverse box.
+.PP
+By default directories are sorted before files but this can be changed
+from the
+.\"LINK2"
+Panel options
+.\"Panel options"
+menu (option
+.BR "Mix all files" ).
+.\"NODE "    Filter..."
+.SH "    Filter..."
+The filter command allows you to specify a shell pattern (for example
+.BR "*.tar.gz" )
+which the files and directories must match to be shown.
+The
+.\"LINK2"
+input line
+.\"Input Line Keys"
+allow enter the pattern of file/directory names that will be shown
+in the panel.
+.PP
+When
+.I Files only
+checkbox is on, only files will be matched to the filter, and all
+directories will be shown. Otherwise, as files as directories will
+be filtered. When
+.I Shell Patterns
+checkbox is on, the regular expression is much like the filename globbing
+in the shell (* standing for zero or more characters and ? standing
+for one character). Otherwise, the matching of files/directoris is done
+with normal regular expressions (see ed(1)). When
+.I Case sensitive
+checkbox is on, the filtering will be case sensitive characters. Otherwise,
+the case will be ignored.
+.\"NODE "    Reread"
+.SH "    Reread"
+The reread command reload the list of files in the directory. It is
+useful if other processes have created or removed files.
+.\"NODE "  File Menu"
+.SH "  File Menu"
+Midnight Commander uses the F1 \- F10 keys as keyboard shortcuts
+for commands appearing in the file menu.  The escape sequences for the
+function keys are terminfo capabilities kf1 trough kf10.  On terminals
+without function key support, you can achieve the same functionality by
+pressing the Esc key and then a number in the range 1 through 9 and 0
+(corresponding to F1 to F9 and F10 respectively).
+.PP
+The File menu has the following commands (keyboard shortcuts in parentheses):
+.PP
+.B Help (F1)
+.PP
+Invokes the built\-in hypertext help viewer. Inside the
+.\"LINK2"
+help viewer\&,
+.\"Contents"
+you can use the Tab key to select the next link and the Enter key to
+follow that link. The keys Space and Backspace are used to move
+forward and backward in a help page. Press F1 again to get the full
+list of accepted keys.
+.PP
+.B Menu (F2)
+.PP
+Invoke the
+.\"LINK2"
+user menu\&.
+.\"Edit Menu File"
+The user menu provides an easy way to provide users with a menu and
+add extra features to Midnight Commander.
+.PP
+.B View (F3, F13)
+.PP
+View the currently selected file. By default this invokes the
+.\"LINK2"
+Internal File Viewer
+.\"Internal File Viewer"
+but if the option "Use internal view" is off, it invokes an external
+file viewer specified by the
+.B VIEWER
+environment variable.  If
+.B VIEWER
+is undefined, the
+.B PAGER
+environment variable is tried.  If
+.B PAGER
+is also undefined, the "view" command is invoked.  If you use F13
+instead, the viewer will be invoked without doing any formatting or
+preprocessing to the file.
+.P
+See
+.\"LINK2"
+parameters for external viewer
+.\"Parameters for external editor or viewer"
+for explain how you may specify an extended command line options
+for external viewers.
+.PP
+.B Filtered View (Alt\-!)
+.PP
+This command prompts for a command
+and its arguments (the argument defaults to the currently selected
+file name), the output from such command is shown in the internal file
+viewer.
+.PP
+.B Edit (F4, F14)
+.PP
+Press F4 to edit the highlighted file.  Press F14 (usually F14)
+to start the editor with a new, empty file.
+Currently they invoke the
+.B vi
+editor, or the editor specified in the
+.B EDITOR
+environment variable, or the
+.\"LINK2"
+Internal File Editor
+.\"Internal File Editor"
+if the use_internal_edit option is on.
+.P
+See
+.\"LINK2"
+parameters for external editor
+.\"Parameters for external editor or viewer"
+for explain how you may specify an extended command line options
+for external editors.
+.PP
+.B Copy (F5, F15)
+.PP
+Press F5 to pop up an input dialog to copy the currently selected file (or
+the tagged files, if there is at least one file tagged) to the
+directory/filename you specify in the input dialog. The destination
+defaults to the directory in the non\-selected panel. Space for destination
+file may be preallocated relative to preallocate_space configure option.
+During this process, you can press C\-c or Esc to abort the operation.
+For details about source mask (which will be usually either * or ^\\(.*\\)$
+depending on setting of Use shell patterns) and possible wildcards in the
+destination see
+.\"LINK2"
+Mask copy/rename\&.
+.\"Mask Copy/Rename"
+.PP
+F15 (usually F15) is similar, but defaults to the directory in the
+selected panel. It always operates on the selected file, regardless of
+any tagged files.
+.PP
+On some systems, it is possible to do the copy in the background by
+clicking on the background button (or pressing Alt\-b in the dialog
+box).  The
+.\"LINK2"
+Background Jobs
+.\"Background jobs"
+is used to control the background process.
+.PP
+.B Link (C\-x l)
+.PP
+Create a hard link to the current file.
+.PP
+.B Absolute symlink (C\-x s)
+.PP
+Create a absolute symbolic link to the current file.
+.PP
+.B Relative symLink (C\-x v)
+.PP
+Create a relative symbolic link to the current file.
+.PP
+To those of you who don't know what links are: creating a link to a file
+is a bit like copying the file, but both the source filename and the destination
+filename represent the same file image. For example, if you edit one of these
+files, all changes you make will appear in both files. Some people call
+links aliases or shortcuts.
+.PP
+A hard link appears as a real file. After making it, there is no way of
+telling which one is the original and which is the link. If you delete
+either one of them the other one is still intact. It is very difficult
+to notice that the files represent the same image. Use hard links when
+you don't even want to know.
+.PP
+A symbolic link is a reference to the name of the original file. If
+the original file is deleted the symbolic link is useless. It is quite
+easy to notice that the files represent the same image. Midnight
+Commander shows an "@"\-sign in front of the file name if it is a
+symbolic link to somewhere (except to directory, where it shows a tilde (~)).
+The original file which the link points to is shown on mini\-status line if the
+.I "Show mini\-status"
+option is enabled. Use symbolic links when you want to avoid the
+confusion that can be caused by hard links.
+.PP
+When you press "C\-x s" Midnight Commander will automatically fill in the
+complete path+filename of the original file and suggest a name for the link.
+You can change either one.
+.PP
+Sometimes you may want to change the absolute path of the original into
+a relative path. An absolute path starts from the root directory:
+.PP
+.I /home/frodo/mc/mc \-> /home/frodo/new/mc
+.PP
+A relative link describes the original file's location starting from the
+location of the link itself:
+.PP
+.I /home/frodo/mc/mc \-> ../new/mc
+.PP
+You can force Midnight Commander to suggest a relative path by pressing
+"C\-x v" instead of "C\-x s".
+.PP
+.B Rename/Move (F6, F16)
+.PP
+Press F6 to pop up an input dialog to copy the currently selected file (or
+the tagged files, if there is at least one file tagged) to the
+directory/filename you specify in the input dialog.  The destination
+defaults to the directory in the non\-selected panel. For more details
+look at Copy (F5) operation above, most of the things are quite similar.
+.PP
+F16 (usually F16) is similar, but defaults to the directory in the
+selected panel. It always operates on the selected file, regardless of
+any tagged files.
+.PP
+On some systems, it is possible to do the copy in the background by
+clicking on the background button (or pressing Alt\-b in the dialog
+box).  The
+.\"LINK2"
+Background Jobs
+.\"Background jobs"
+is used to control the background process.
+.PP
+.B Mkdir (F7)
+.PP
+Pop up an input dialog and creates the directory specified.
+.PP
+.B Delete (F8)
+.PP
+Delete the currently selected file or the tagged files in the
+currently selected panel. During the process, you can press C\-c or
+Esc to abort the operation.
+.PP
+.B Quick cd (Alt\-c)
+Use the
+.\"LINK2"
+quick cd
+.\"Quick cd"
+command if you have full command line and want to cd somewhere.
+.PP
+.B Select group (+)
+.PP
+This is used to select (tag) a group of files. Midnight Commander
+will prompt for a selection options. When
+.I Files only
+checkbox is on, only files will be selected.  If
+.I Files only
+is off, as files as directories will be selected.
+When
+.I Shell Patterns
+checkbox is on, the regular expression is much like the filename globbing
+in the shell (* standing for zero or more characters and ?  standing
+for one character). If
+.I Shell Patterns
+is off, then the tagging of files is done with normal regular
+expressions (see ed (1)). When
+.I Case sensitive
+checkbox is on, the selection will be case sensitive characters.
+If
+.I Case sensitive
+is off, the case will be ignored.
+.PP
+.B Unselect group (\\\\)
+.PP
+Used to unselect a group of files. This is the opposite of the
+.I "Select group"
+command.
+.PP
+.B Quit (F10, S\-F10)
+.PP
+Terminate Midnight Commander. S\-F10 is used when you want to
+quit and you are using the shell wrapper.  S\-F10 will not take you
+to the last directory you visited with Midnight Commander, instead
+it will stay at the directory where you started Midnight Commander.
+.\"NODE "    Quick cd"
+.SH "    Quick cd"
+This command is useful if you have a full command line and want to
+.\"LINK2"
+cd
+.\"The cd internal command"
+somewhere without having to yank and paste the command line. This command
+pops up a small dialog, where you enter everything you would enter after

+"Find file"
+.\"Find File"
+command allows you to search for a specific file.
+.PP
+The "Swap panels" command swaps the contents of the two directory panels.
+.PP
+The "Switch panels on/off" command shows the output of the last shell command.
+This works only on xterm and on Linux and FreeBSD console.
+.PP
+The "Compare directories" command compares the directory
+panels with each other. You can then use the Copy (F5) command to make
+the panels identical. There are three compare methods. The quick method
+compares only file size and file date. The thorough method makes a
+full byte\-by\-byte compare. The thorough method is not available if the
+machine does not support the mmap(2) system call.  The size\-only
+compare method just compares the file sizes and does not check the
+contents or the date times, it just checks the file size.
+.PP
+The
+.\"LINK2"
+"External panelize"
+.\"External panelize"
+allows you to execute an external program, and make the output of that
+program the contents of the current panel.
+.PP
+The "Command history" command shows a list of typed commands. The

+The Directory Tree command shows a tree figure of the directories. You
+can select a directory from the figure and Midnight Commander will
+change to that directory.
+.PP
+There are two ways to invoke the tree. The real directory tree command
+is available from Commands menu. The other way is to select tree view
+from the Left or Right menu.
+.PP
+To get rid of long delays, Midnight Commander creates the tree
+figure by scanning only a small subset of all the directories. If the
+directory which you want to see is missing, move to its parent
+directory and press C\-r (or F2).
+.PP
+You can use the following keys:
+.TP
+.\"LINK2"
+General movement keys
+.\"General Movement Keys"
+are accepted.
+.TP
+.B Enter.
+In the directory tree, exits the directory tree and changes to this
+directory in the current panel. In the tree view, changes to this

+current panel.
+.TP
+.B C\-r, F2 (Rescan).
+Rescan this directory. Use this when the tree figure is out of date:
+it is missing subdirectories or shows some subdirectories which don't
+exist any more.

+.PP
+In the dynamic navigation mode you can use the Up and Down keys to
+select a sibling directory, the Left key to move to the parent

+button you can select the start directory from the
+.\"LINK2"
+directory tree
+.\"Directory Tree"
+figure.
+.PP
+The "File name" input field contains a filename pattern to be searched
+for. It is interpreted as a shell pattern or as a regular expression
+depending on the state of the "Using shell patterns" checkbox. An empty
+value is valid and matches any file name.
+.PP
+The "Content" input field contains a string to search for within the

+.PP
+You can start the search by pressing the OK button.
+During the search you can stop from the Stop button and continue from
+the Start button.
+.PP
+You can browse the filelist with the up and down arrow keys. The Chdir
+button will change to the directory of the currently selected
+file. The Again button will ask for the parameters for a new
+search. The Quit button quits the search operation. The Panelize
+button will place the found files to the current directory panel so
+that you can do additional operations on them (view, copy, move,
+delete and so on). To return to the normal file listing, change directory
+to "..".
+.PP
+The 'Enable ignore directories' checkbox and input field below it
+allow one to set up the list of directories that should be skip during the search
+files (for example, you may want to avoid searches on a CD\-ROM or on a NFS
+directory that is mounted across a slow link). List components must be separated
+with a colon, here is an example:
+.PP
+.nf

+.fi
+.PP
+Relative paths are supported also. The following example shows how to skip special
+directories of version control systems:
+.nf
+/cdrom:/nfs/wuarchive:/afs:.svn:.git:CVS
+.fi
+.PP
+Attention: input field can contain a dot (.), this means the current absolute path.
+.PP
+You may consider using the
+.\"LINK2"
+External panelize
+.\"External panelize"
+command for some operations. Find file command is for simple queries
+only, while using External panelize you can do as mysterious searches
+as you would like.
+.\"NODE "    External panelize"
+.SH "    External panelize"
+The External panelize allows you to execute an external program, and
+make the output of that program the contents of the current panel.
+.PP
+For example, if you want to manipulate in one of the panels all the
+symbolic links in the current directory, you can use external
+panelization to run the following command:
+.PP
+.nf
+find . \-type l \-print
+.fi
+.PP
+Upon command completion, the directory contents of the panel will no
+longer be the directory listing of the current directory, but all the
+files that are symbolic links.
+.PP
+If you want to panelize all of the files that have been downloaded
+from your FTP server, you can use this awk command to extract the file
+name from the transfer log files:
+.PP
+.nf
+awk '$9 ~! /incoming/ { print $9 }' < /var/log/xferlog
+.fi
+.PP
+You may want to save often used panelize commands under a descriptive name,
+so that you can recall them quickly. You do this by typing the command on
+the input line and pressing Add new button. Then you enter a name under
+which you want the command to be saved. Next time, you just choose that
+command from the list and do not have to type it again.
+.\"NODE "    Hotlist"
+.SH "    Hotlist"
+The Directory hotlist command shows the labels of the directories
+in the directory hotlist. Midnight Commander will change to the
+directory corresponding to the selected label.  From the hotlist dialog,
+you can remove already created label/directory pairs and add new ones.
+To add new directories quickly, you can use the Add to hotlist command
+(C\-x h), which adds the current directory into the directory hotlist,
+asking just for the label for the directory.
+.PP
+This makes cd to often used directories faster. You may consider using the
+CDPATH variable as described in
+.\"LINK2"
+internal cd command
+.\"The cd internal command"
+description.
+.\"NODE "    Edit Extension File"
+.SH "    Edit Extension File"
+This will invoke your editor on the file
+.IR ~/.config/mc/mc.ext.ini .

+here.
+.\"NODE "    Edit Menu File"
+.SH "    Edit Menu File"
+The user menu is a menu of useful actions that can be customized by
+the user. When you access the user menu, the
+file .mc.menu from the current directory is used if it exists,
+but only if it is owned by user or root and is not world\-writable.
+If no such file found, ~/.config/mc/menu is tried in the same way,
+and otherwise mc uses the default system\-wide menu
+%pkgdatadir%/mc.menu.
+.PP
+The format of the menu file is very simple. Lines that start with
+anything but space or tab are considered entries for the menu (in
+order to be able to use it like a hot key, the first character should
+be a letter). All the lines that start with a space or a tab are the
+commands that will be executed when the entry is selected.
+.PP
+When an option is selected all the command lines of the option are
+copied to a temporary file in the temporary directory (usually
+/usr/tmp) and then that file is executed. This allows the user to put
+normal shell constructs in the menus. Also simple macro substitution
+takes place before executing the menu code. For more information, see
+.\"LINK2"
+macro substitution\&.
+.\"Macro Substitution"
+.PP
+Here is a sample mc.menu file:
+.PP
+.nf

+.PP
+.B Default Conditions
+.PP
+Each menu entry may be preceded by a condition. The condition must
+start from the first column with a '=' character. If the condition is
+true, the menu entry will be the default entry.
+.PP
+.nf
+Condition syntax: 	= <sub\-cond>
+  or:			= <sub\-cond> | <sub\-cond> ...
+  or:			= <sub\-cond> & <sub\-cond> ...
+
+Sub\-condition is one of following:
+
+  y <pattern>		syntax of current file matching pattern?
+			(for edit menu only)
+  f <pattern>		current file matching pattern?
+  F <pattern>		other file matching pattern?
+  d <pattern>		current directory matching pattern?
+  D <pattern>		other directory matching pattern?
+  t <type>		current file of type?
+  T <type>		other file of type?
+  x <filename>		is it executable filename?
+  ! <sub\-cond>		negate the result of sub\-condition
+.fi
+.PP
+Pattern is a normal shell pattern or a regular expression, according
+to the shell patterns option. You can override the global value of
+the shell patterns option by writing "shell_patterns=x" on the first
+line of the menu file (where "x" is either 0 or 1).
+.PP
+Type is one or more of the following characters:
+.PP
+.nf
+  n	not a directory
+  r	regular file
+  d	directory
+  l	link
+  c	character device
+  b	block device
+  f	FIFO (pipe)
+  s	socket
+  x	executable file
+  t	tagged
+.fi
+.PP
+For example 'rlf' means either regular file, link or fifo. The 't'
+type is a little special because it acts on the panel instead of the
+file. The condition '=t t' is true if there are tagged files in the
+current panel and false if not.
+.PP
+If the condition starts with '=?' instead of '=' a debug trace will be
+shown whenever the value of the condition is calculated.
+.PP
+The conditions are calculated from left to right. This means
+.nf
+	= f *.tar.gz | f *.tgz & t n
+.fi
+is calculated as
+.nf
+	( (f *.tar.gz) | (f *.tgz) ) & (t n)
+.fi

+.\"NODE "    Configuration"
+.SH "    Configuration"
+The options in this dialog are divided into several groups: "File
+operation options", "Esc key mode", "Pause after run" and "Other options".
+.PP
+.B File operation options
+.PP
+.I Verbose operation.
+This toggles whether the file Copy, Rename and Delete operations are
+verbose (i.e., display a dialog box for each operation). If you have a
+slow terminal, you may wish to disable the verbose operation. It is
+automatically turned off if the speed of your terminal is less than
+9600 bps.
+.PP
+.I Compute totals.
+If this option is enabled, Midnight Commander computes total byte
+sizes and total number of files prior to any Copy, Rename and Delete
+operations. This will provide you with a more accurate progress bar
+at the expense of some speed. This option has no effect, if
+.I Verbose  operation
+is disabled.
+.PP
+.I Classic progressbar.
+If this option is enabled, the progressbar of Copy/Move/Delete operations
+is always grown form left to right. If disabled, the growing direction
+of progressbar follows to direction of Copy/Move/Delete operation:
+from left panel to right one and vice versa. Enabled by default.
+.PP
+.I Mkdir autoname.
+When you press F7 to create a new directory, the input line in popup dialog
+will be filled by name of current file or directory in active panel.
+Disabled by default.
+.PP
+.I Preallocate space.
+Preallocate space for whole target file, if possible, before copy operation.
+Disabled by default.
+.PP
+.B Esc key mode.
+.PP
+By default, Midnight Commander treats the Esc key as a key prefix.
+Therefore, you should press Esc code twice to exit a dialog. But there is
+a possibility to use a single press of Esc key for that action.
+.PP
+.I Single press.
+By default this option is disabled. If you'll enable it, the Esc key
+will act as a prefix key for set up time interval (see
+.I Timeout
+option below), and if no extra keys have arrived, then the Esc key
+is interpreted as a cancel key (Esc Esc).
+.PP
+.I Timeout.
+This options is used to setup the time interval (in microseconds)
+for single press of Esc key. By default, this interval is one second
+(1000000 microseconds). Also the timeout can be set via KEYBOARD_KEY_TIMEOUT_US
+environment variable (also in microseconds), which has higher priority
+than Timeout option value.
+.PP
+.B Pause after run
+.PP
+After executing your commands, Midnight Commander can pause, so
+that you can examine the output of the command.  There are three
+possible settings for this variable:
+.PP
+.I Never.
+Means that you do not want to see the output of your command.  If you
+are using the Linux or FreeBSD console or an xterm, you will be able to
+see the output of the command by typing C\-o.
+.PP
+.I On dumb terminals.
+You will get the pause message on terminals that are not capable of
+showing the output of the last command executed (any terminal that is
+not an xterm or the Linux console).
+.PP
+.I Always.
+The program will pause after executing all of your commands.
+.PP
+.B Other options
+.PP
+.I Use internal editor.
+If this option is enabled, the built\-in file editor is used to edit
+files. If the option is disabled, the editor specified in the
+.B EDITOR
+environment variable is used.
+If no editor is specified,
+.B vi
+is used.  See the section on the
+.\"LINK2"
+internal file editor\&.
+.\"Internal File Editor"
+.PP
+.I Use internal viewer.
+If this option is enabled, the built\-in file viewer is used to view
+files. If the option is disabled, the pager specified in the
+.B PAGER
+environment variable is used.
+If no pager is specified, the
+.B view
+command is used.  See the section on the
+.\"LINK2"
+internal file viewer\&.
+.\"Internal File Viewer"
+.PP
+.I Ask new file name.
+If this option is enabled, file name is asked before open new file in editor.
+.PP
+.I Auto menus.
+If this option is enabled, the user menu will be invoked at startup.
+Useful for building menus for non\-unixers.
+.PP
+.I Drop down menus.
+When this option is enabled, the pull down menus will be activated as
+soon as you press the F9 key. Otherwise, you will only get the menu title,
+and you will have to activate the menu either with the arrow keys or with
+the hotkeys. It is recommended if you are using hotkeys.
+.PP
+.I Shell Patterns.
+By default the Select, Unselect and Filter commands will use shell\-like
+regular expressions. The following conversions are performed to achieve
+this: the '*' is replaced by '.*' (zero or more characters); the '?'
+is replaced by '.' (exactly one character) and '.' by the literal
+dot. If the option is disabled, then the regular expressions are the
+ones described in ed(1).
+.PP
+.I Complete: show all.
+By default, Midnight Commander pops up all possible
+.\"LINK2"
+completions
+.\"Completion"
+if the completion is ambiguous only when you press
+.B Alt\-Tab
+for the second time.  For the first time, it just completes as much as
+possible and beeps in the case of ambiguity.  Enable this option if you
+want to see all possible completions even after pressing
+.B Alt\-Tab
+the first time.
+.PP
+.I Rotating dash.
+If this option is enabled, the
+Midnight Commander shows a rotating dash in the upper right corner
+as a work in progress indicator.
+.PP
+.I Cd follows links.
+This option, if set, causes Midnight Commander to follow the
+logical chain of directories when changing current directory
+either in the panels, or using the cd command. This is the default
+behavior of bash. When unset, Midnight Commander follows the
+real directory structure, so cd .. if you've entered that directory
+through a link will move you to the current directory's real parent
+and not to the directory where the link was present.
+.PP
+.I Safe delete.
+If this option is enabled, deleting files and directory hotlist entries
+unintentionally becomes more difficult.  The default selection in the
+confirmation dialogs for deletion changes from
+.B Yes
+to
+.BR No .
+This option is disabled by default.
+.PP
+.I Safe overwrite.
+If this option is enabled, overwriting files unintentionally becomes
+more difficult.  The default selection in the overwrite confirmation dialog
+changes from
+.B Yes
+to
+.BR No .
+This option is disabled by default.
+.PP
+.I Auto save setup.
+If this option is enabled, when you exit Midnight Commander, the
+configurable options of Midnight Commander are saved in the
+~/.config/mc/ini file.
+.\"NODE "    Layout"
+.SH "    Layout"
+The layout dialog gives you a possibility to change the general layout
+of screen. The options in this dialog are divided into several groups:
+"Panel split", "Console output" and "Other options".
+.PP
+.B Panel split
+.PP
+The rest of the screen area is used for the two directory panels. You
+can specify whether the area is split to the panels in
+.I Vertical
+or
+.I Horizontal
+direction. Panel layout can be changed using Alt\-, (Alt\-comma) shortcut.
+.PP
+.I Equal split.
+By default, panels have equal sizes. Using this option you can specify
+an unequal split.
+.PP
+.B Console output
+.PP
+On the Linux or FreeBSD console you can specify how many lines are shown
+in the output window. This option is available if Midnight Commander runs
+on native console only.
+.PP
+.B Other options
+.PP
+.I Menu bar visible.
+If enabled, main menu of Midnight Commander is always visible on the top row
+of screen above panels. Enabled by default.
+.PP
+.I Command prompt.
+If enabled, command line is available. Enabled by default.
+.PP
+.I Keybar visible.
+If enabled, 10 labels associated with F1\-F10 keys are located at the bottom
+row of screen. Enabled by default.
+.PP
+.I Hintbar visible.
+If enabled, the one\-line hints are visible below panels. Enabled by default.
+.PP
+.I XTerm window title.
+When run in a terminal emulator for X11, Midnight Commander sets the
+terminal window title to the current working directory and updates it
+when necessary.  If your terminal emulator is broken and you see some
+incorrect output on startup and directory change, turn off this option.
+Enabled by default.
+.PP
+.I Show free space.
+If enabled, free space and total space of current file system is shown
+at the bottom frame of panel. Enabled by default.
+.\"NODE "    Panel options"
+.SH "    Panel options"
+.B Main panel options
+.PP
+.I Show mini\-status.
+If enabled, one line of status information about the currently selected item
+is shown at the bottom of the panels. Enabled by default.
+.PP
+.I Use SI size units.
+If this option is enabled, Midnight Commander will use SI prefixes (base 10)
+when displaying any byte sizes. If disabled (default), Midnight Commander will
+use IEC prefixes (base 2).
+.PP
+.I Mix all files.
+If this option is enabled, all files and directories are shown mixed
+together.  If the option is disabled (default), directories (and links to
+directories) are shown at the beginning of the listing, and other files below.
+.PP
+.I Show backup files.
+If enabled, Midnight Commander will show files ending with a tilde.
+Otherwise, they won't be shown (like GNU's ls option \-B). Enabled by default.
+.PP
+.I Show hidden files.
+If enabled, Midnight Commander will show all files that start with
+a dot (like ls \-a). Disabled by default.
+.PP
+.I Fast directory reload.
+If this option is enabled, Midnight Commander will use a trick to
+determine if the directory contents have changed.  The trick is to reload
+the directory only if the i\-node of the directory has changed; this means
+that reloads only happen when files are created or deleted.  If what
+changes is the i\-node for a file in the directory (file size changes,
+mode or owner changes, etc) the display is not updated.  In these cases,
+if you have the option on, you have to rescan the directory manually
+(with C\-r). Disabled by default.
+.PP
+.I Mark moves down.
+If enabled, the selection bar will move down when you mark a file (with
+Insert key). Enabled by default.
+.PP
+.I Reverse files only.
+Allow revert selection of files only. Enabled by default.
+If enabled, the reverse selection is applied to files only, not to directories.
+The selection of directories is untouched. If off, the reverse selection
+is applied to files as well to directories: all unselected items become
+selected, and vice versa.
+.PP
+.I Simple swap.
+If both panels contain file listing, simple swap means that panels exchange
+its screen positions: left panel become right one, and vice versa. If this
+option is unchecked, file listing panels exchange its content keeping listing
+format and sort options. Unchecked by default.
+.PP
+.I Auto save panels setup.
+If this option is enabled, when you exit Midnight Commander, the
+current settings of panels are saved in the ~/.config/mc/panels.ini file.
+Disabled by default.
+.PP
+.B Navigation
+.PP
+.I Lynx\-like motion.
+If this option is enabled, you may use the arrows keys to automatically
+chdir if the current selection is a subdirectory and the shell command
+line is empty. By default, this setting is off.
+.PP
+.I Page scrolling.
+If set (the default), panel will scroll by half the display when the
+cursor reaches the end or the beginning of the panel, otherwise it
+will just scroll a file at a time.
+.PP
+.I Center scrolling.
+If set, panel will scroll when the cursor reaches the middle of the
+panel column, only hitting the top or bottom of the panel when actually on
+the first or last file. This behavior applies when scrolling one file
+at a time, and does not apply to the page up/down keys.
+.PP
+.I Mouse page scrolling.
+Controls whenever scrolling with the mouse wheel is done by pages or
+line by line on the panels.
+.PP
+.B File highlight
+.PP
+You can specify whether
+.I permissions
+and
+.I file types
+should be highlighted with distinctive
+.\"LINK2"
+Colors\&.
+.\"Colors"
+If the permission highlighting is enabled, the parts of the
+.I perm
+and

+.\"NODE "    Display bits"
+.SH "    Display bits"
+This is used to configure the range of visible characters on the

+only seven output bits, ISO\-8859\-1 displays all the characters in the
+ISO\-8859\-1 map and full 8 bits is for those terminals that can display
+full 8 bit characters.
+.\"NODE "    Learn keys"
+.SH "    Learn keys"
+This dialog allows you to test and redefine functional keys, cursor
+arrows and some other keys to make them work properly on your terminal.
+They often don't, since many terminal databases are incomplete or broken.
+.PP
+You can move around with the Tab key and with the vi moving keys ('h'
+left, 'j' down, 'k' up and 'l' right).  Once you press any cursor movement
+key and it is recognized, you can use that key as well.
+.PP
+You can test keys just by pressing each of them.  When you press a
+key and it is recognized properly, OK should appear next to the name
+of that key.  Once a key is marked OK it starts working as usually,
+e.g. F1 pressed the first time will just check that the F1 key works,
+but after that it will show help.  The same applies to the arrow keys.
+The Tab key should be working always.
+.PP
+If some keys do not work properly then you won't see OK appear after
+pressing one of these.  Then you may want to redefine it.  Do it by pressing
+the button with the name of that key (either by the mouse or by Enter
+or Space after selecting the button with Tab or arrows).  Then a message
+box will appear asking you to press that key.  Do it and wait until the
+message box disappears.  If you want to abort, just press Escape once
+and wait.
+.PP
+When you finish with all the keys, you can Save them.  The definitions
+for the keys you have redefined will be written into the [terminal:TERM]
+section of your ~/.config/mc/ini file (where TERM is the name of your current
+terminal).  The definitions of the keys that were already working properly
+are not saved.
+.\"NODE "    Virtual FS"
+.SH "    Virtual FS"
+This option gives you control over the settings of the
+.\"LINK2"
+Virtual File System\&.
+.\"Virtual File System"
+.PP
+Midnight Commander keeps in memory the information related to some
+of the virtual file systems to speed up the access to the files in the
+file system (for example, directory listings fetched from FTP servers).
+.PP
+Also, in order to access the contents of compressed files (for example,
+compressed tar files), Midnight Commander needs to create temporary
+uncompressed files on your disk.
+.PP
+Since both the information in memory and the temporary files on disk
+take up resources, you may want to tune the parameters of the cached
+information to decrease your resource usage or to maximize the speed of
+access to frequently used file systems.
+.PP
+Because of the format of the tar archives, the
+.I Tar filesystem
+needs to read the whole file just to load the file entries.  Since most
+tar files are usually kept compressed (plain tar files are species in
+extinction), the tar file system has to uncompress the file on the disk
+in a temporary location and then access the uncompressed file as a
+regular tar file.
+.PP
+Now, since we all love to browse files and tar files all over the disk,
+it's common that you will leave a tar file and then re\-enter it later.
+Since decompression is slow, Midnight Commander will cache the
+information in memory for a limited time.  When the timeout expires, all
+the resources associated with the file system are released.  The default
+timeout is set to one minute.
+.PP
+The
+.\"LINK2"
+FTP File System
+.\"FTP File System"
+(ftpfs) allows you to browse directories on remote FTP servers.  It has
+several options.
+.PP
+.I ftp anonymous password
+is the password used when you login as "anonymous".  Some sites require
+a valid e\-mail address.  On the other hand, you probably don't want to
+give your real e\-mail address to untrusted sites, especially if you are
+not using spam filtering.
+.PP
+ftpfs keeps the directory listing it fetches from a FTP server in a cache.
+The cache expire time is configurable with the
+.I ftpfs directory cache timeout
+option.  A low value for this option may slow down every operation on
+the ftpfs because every operation would require sending a request to the
+FTP server.
+.PP
+You can define an FTP proxy host for doing FTP.  Note that most modern
+firewalls are fully transparent at least for passive FTP (see below), so
+FTP proxies are considered obsolete.
+.PP
+If
+.I Always use ftp proxy
+is not set, you can use the exclamation sign to enable proxy for certain
+hosts.  See
+.\"LINK2"
+FTP File System
+.\"FTP File System"
+for examples.
+.PP
+If this option is set, the program will do two things: consult the
+%sysconfdir%/mc/mc.no_proxy file for lines containing host names that
+are local (if the host name starts with a dot, it is assumed to be a
+domain) and to assume that any hostnames without dots in their names are
+directly accessible.  All other hosts will be accessed through the
+specified FTP proxy.
+.PP
+You can enable using
+.I ~/.netrc
+file, which keeps login names and passwords for ftp servers.  See netrc
+(5) for the description of the .netrc format.
+.PP
+.I Use passive mode
+enables using FTP passive mode, when the connection for data transfer is
+initiated by the client, not by the server.  This option is recommended
+and enabled by default.  If this option is turned off, the data
+connection is initiated by the server.  This may not work with some
+firewalls.
+.\"NODE "    Save Setup"

+.\"NODE "File Operations"
+.SH "File Operations"
+When you copy, move or delete files, Midnight Commander shows the
+file operations dialog.  It shows the files currently being processed
+and uses up to three progress bars.  The file bar indicates the
+percentage of the current file that has been processed so far.  The
+count bar shows how many of the tagged files have been handled.  The
+bytes bar indicates the percentage of the total size of the tagged files
+that has been handled.  If the verbose option is off, the file and bytes
+bars are not shown.
+.PP
+There are two buttons at the bottom of the dialog. Pressing the Skip
+button will skip the rest of the current file. Pressing the Abort
+button will abort the whole operation, the rest of the files are
+skipped.
+.PP
+There are three other dialogs which you can run into during the file
+operations.
+.PP
+The error dialog informs about error conditions and has three choices.
+Normally you select either the Skip button to skip the file or the Abort
+button to abort the operation altogether.  You can also select the Retry
+button if you fixed the problem from another terminal.
+.PP
+The replace dialog is shown when you attempt to copy or move a file on
+the top of an existing file.  The dialog shows the dates and sizes of
+the both files.  Press the Yes button to overwrite the file, the No
+button to skip the file, the All button to overwrite all the files, the
+None button to never overwrite and the Update button to overwrite if the
+source file is newer than the target file.  You can abort the whole
+operation by pressing the Abort button.
+.PP
+The recursive delete dialog is shown when you try to delete a directory
+which is not empty.  Press the Yes button to delete the directory
+recursively, the No button to skip the directory, the All button to
+delete all the directories and the None button to skip all the non\-empty
+directories.  You can abort the whole operation by pressing the Abort
+button.  If you selected the Yes or All button you will be asked for a
+confirmation.  Type "yes" only if you are really sure you want to do the
+recursive delete.
+.PP
+If you have tagged files and perform an operation on them only the files
+on which the operation succeeded are untagged. Failed and skipped files
+are left tagged.
+.\"NODE "Mask Copy/Rename"
+.SH "Mask Copy/Rename"
+The copy/move operations let you translate the names of files in an
+easy way.  To do it, you have to specify the correct source mask and
+usually in the trailing part of the destination specify some wildcards.
+All the files matching the source mask are copied/renamed according to
+the target mask.  If there are tagged files, only the tagged files
+matching the source mask are renamed.
+.PP
+There are other options which you can set:
+.PP
+.B Follow links
+.PP
+determines whether make the symlinks and hardlinks in the source
+directory (recursively in subdirectories) new links in the target
+directory or whether would you like to copy their content.
+.PP
+.B Dive into subdirs
+.PP
+determines the behavior when the source directory is about to be copied,
+but the target directory already exists.  The default action is to copy
+the contents of the source directory into the target directory.
+Enabling this option causes copying the source directory itself into the
+target directory.
+.PP
+For example, you want to copy directory
+.I /foo
+containing file
+.I bar
+to
+.IR /bla/foo ,
+which is an already existing directory.  Normally (when
+.B Dive into subdirs
+is not set), mc would copy file
+.I /foo/bar
+into the file
+.IR /bla/foo/bar .
+By enabling this option the
+.I /bla/foo/foo
+directory will be created, and
+.I /foo/bar
+will be copied into
+.IR /bla/foo/foo/bar .
+.PP
+.B Preserve attributes
+.PP
+determines whether to preserve the permissions, timestamps and (if you
+are root) the ownership of the original files.  If this option is not
+set, the current value of the umask will be respected.
+.PP
+.B Use shell patterns
+.PP
+When this option is on you can use the '*' and '?' wildcards in the source
+mask. They work like they do in the shell. In the target mask only the '*'
+and '\\<digit>' wildcards are allowed. The first '*' wildcard in the target
+mask corresponds to the first wildcard group in the source mask,
+the second '*' corresponds to the second group and so on.  The '\\1' wildcard
+corresponds to the first wildcard group in the source mask, the '\\2' wildcard
+corresponds to the second group and so on all the way up to '\\9'.
+The '\\0' wildcard is the whole filename of the source file.
+.PP
+Two examples:
+.PP
+If the source mask is "*.tar.gz", the destination is "/bla/*.tgz" and the
+file to be copied is "foo.tar.gz", the copy will be "foo.tgz" in "/bla".
+.PP
+Suppose you want to swap basename and extension so that "file.c" would
+become "c.file" and so on.  The source mask for this is "*.*" and the
+destination is "\\2.\\1".
+.PP
+.B Use shell patterns off
+.PP
+When the shell patterns option is off the MC doesn't do automatic
+grouping anymore. You must use '\\(...\\)' expressions in the source
+mask to specify meaning for the wildcards in the target mask. This is
+more flexible but also requires more typing. Otherwise target masks
+are similar to the situation when the shell patterns option is on.
+.PP
+Two examples:
+.PP
+If the source mask is "^\\(.*\\)\\.tar\\.gz$", the destination is
+"/bla/*.tgz" and the file to be copied is "foo.tar.gz", the copy
+will be "/bla/foo.tgz".
+.PP
+Let's suppose you want to swap basename and extension so that "file.c"
+will become "c.file" and so on. The source mask for this is
+"^\\(.*\\)\\.\\(.*\\)$" and the destination is "\\2.\\1".
+.PP
+.B Case Conversions
+.PP
+You can also change the case of the filenames.  If you use '\\u'
+or '\\l' in the target mask, the next character will be converted to
+uppercase or lowercase correspondingly.
+.PP
+If you use '\\U' or '\\L' in the target mask, the next characters will
+be converted to uppercase or lowercase correspondingly up to the
+next '\\E' or next '\\U', '\\L' or the end of the file name.
+.PP
+The '\\u' and '\\l' are stronger than '\\U' and '\\L'.
+.PP
+For example, if the source mask is '*' (
+.I Use shell patterns
+on) or '^\\(.*\\)$' (
+.I Use shell patterns
+off) and the target mask is '\\L\\u*' the file names will be converted
+to have initial upper case and otherwise lower case.
+.PP
+You can also use '\\' as a quote character. For example, '\\\\' is
+a backslash and '\\*' is an asterisk.
+.PP
+.B Stable symlinks
+.PP
+commands Midnight Commander, that it should change symlinks in the target,
+so that they'll point to the same location as it did before. With absolute
+symbolic links this does nothing, but if you have a relative one, it will
+recompute its value, adding necessary ../ and other directory parts and making
+the value as short as possible (most modern filesystems keep short symlinks
+inside inodes and thus don't waste much disk space).

+.SH "  Tar File System"
+The tar file system provides you with read\-only access to your tar
+files and compressed tar files by using the chdir command.  To change
+your directory to a tar file, you change your current directory to the
+tar file by using the following syntax:
+.PP
+.I /filename.tar/utar://[dir\-inside\-tar]
+.PP
+The mc.ext.ini file already provides a shortcut for tar files, this means
+that usually you just point to a tar file and press return to enter
+into the tar file, see the
+.\"LINK2"
+Edit Extension File
+.\"Edit Extension File"
+section for details on how this is done.
+.PP
+Examples:
+.PP
+.nf
+    mc\-3.0.tar.gz/utar://mc\-3.0/vfs
+    /ftp/GCC/gcc\-2.7.0.tar/utar://
+.fi
+.PP
+The latter specifies the full path of the tar archive.

+.\"NODE "  Undelete File System"
+.SH "  Undelete File System"
+On Linux systems, if you asked configure to use the ext2fs undelete
+facilities, you will have the undelete file system available.
+Recovery of deleted files is only available on ext2 file systems.  The
+undelete file system is just an interface to the ext2fs library to
+retrieve all of the deleted files names on an ext2fs and provides and
+to extract the selected files into a regular partition.
+.PP
+To use this file system, you have to chdir into the special file name
+formed by the "undel://" prefix and the file name where the actual
+file system resides.
+.PP
+For example, to recover deleted files on the second partition of the
+first SCSI disk on Linux, you would use the following path name:
+.PP
+.nf
+    undel://sda2
+.fi
+.PP
+It may take a while for the undelfs to load the required information
+before you start browsing files there.
+.\"NODE "  EXTernal File System"
+.SH "  EXTernal File System"
+.B extfs
+allows you to integrate numerous features and file types into GNU Midnight
+Commander in an easy way, by writing scripts.
+.PP
+Extfs filesystems can be divided into two categories:
+.PP
+1. Stand\-alone filesystems, which are not associated with any existing
+file.  They represent certain system\-wide data as a directory tree.
+You can invoke them by typing
+.I "cd fsname://"
+where fsname is an extfs short name (see below).  Examples of such
+filesystems include audio (list audio tracks on the CD) or apt (list of
+all Debian packages in the system).
+.PP
+For example, to list CD\-Audio tracks on your CD\-ROM drive, type
+.PP
+.nf
+  cd audio://
+.fi
+.PP
+2. 'Archive' filesystems (like rpm, patchfs and more), which represent
+contents of a file as a directory tree.  It can consist of 'real' files
+compressed in an archive (urar, rpm) or virtual files, like messages
+in a mailbox (mailfs) or parts of a patch (patchfs).  To access such
+filesystems
+.I fsname://
+should be appended to the archive name.  Note that the archive itself
+can be on another vfs.
+.PP
+For example, to list contents of a zip archive documents.zip type
+.PP
+.nf
+  cd documents.zip/uzip://
+.fi
+.PP
+In many aspects, you could treat extfs like any other directory.  For
+instance, you can add it to the hotlist or change to it from directory
+history.  An important limitation is that you cannot invoke shell
+commands inside extfs, just like any other non\-local VFS.
+.PP
+Common extfs scripts included with Midnight Commander are:
+.TP
+.B a
+access 'A:' DOS/Windows diskette
+.RI ( "cd a://" ).
+.TP
+.B apt
+front end to Debian's APT package management system
+.RI ( "cd apt://" ).
+.TP
+.B audio
+audio CD ripping and playing
+.RI ( "cd audio://"
+or
+.IR "cd device/audio://" ).
+.TP
+.B bpp
+package of Bad Penguin GNU/Linux distribution
+.RI ( "cd file.bpp/bpp://" ).
+.TP
+.B deb
+package of Debian GNU/Linux distribution
+.RI ( "cd file.deb/deb://" ).
+.TP
+.B dpkg
+Debian GNU/Linux installed packages
+.RI ( "cd deb://" ).
+.TP
+.B hp48
+view and copy files to/from a HP48 calculator
+.RI ( "cd hp48://" ).
+.TP
+.B lslR
+browsing of lslR listings as found on many FTPs
+.RI ( "cd filename/lslR://" ).
+.TP
+.B mailfs
+mbox\-style mailbox files support
+.RI ( "cd mailbox/mailfs://" ).
+.TP
+.B patchfs

+.RI ( "cd filename/patchfs://" ).
+.TP
+.B rpm

+.RI ( "cd rpms://" ).
+.TP
+.B ulha, urar, uzip, uzoo, uar, uha

+.RI ( "cd archive/xxxx://"
+where xxxx is one of:
+.IR ulha ,
+.IR urar ,
+.IR uzip ,
+.IR uzoo ,

+.PP
+You could bind file type/extension to specified extfs as described in the
+.\"LINK2"

+.\"NODE "Colors"
+.SH "Colors"
+Midnight Commander will try to detect if your terminal supports
+color using the terminal database and your terminal name.  Sometimes
+it gets confused, so you may force color mode or disable color mode
+using the \-c and \-b flag respectively.
+.PP
+If the program is compiled with the S\-Lang screen manager instead of
+ncurses, it will also check the variable
+.B COLORTERM,
+if it is set, it has the same effect as the \-c flag.
+.PP
+You may specify terminals that always force color mode
+by adding the
+.I color_terminals
+variable to the Colors section of the initialization file.  This will
+prevent Midnight Commander from trying to detect if your terminal
+supports color.  Example:
+.PP
+.nf
+[Colors]
+color_terminals=linux,xterm
+color_terminals=terminal\-name1,terminal\-name2...
+.fi
+.PP
+The program can be compiled with both ncurses and S\-Lang, ncurses does
+not provide a way to force color mode: ncurses uses just the
+information in the terminal database.
+.PP
+Midnight Commander provides a way to change the default colors.
+Currently the colors are configured using the environment variable
+.B MC_COLOR_TABLE
+or the Colors section in the initialization file.
+.PP
+In the Colors section, the default color map is loaded from the
+.I base_color
+variable.  You can specify an alternate color map for a terminal by
+using the terminal name as the key in this section.  Example:
+.PP
+.nf
+[Colors]
+base_color=
+xterm=menu=magenta:marked=,magenta:markselect=,red
+.fi
+.PP
+The format for the color definition is:
+.PP
+.nf
+  <keyword>=<fgcolor>,<bgcolor>,<attributes>:<keyword>=...
+.fi
+.PP
+The colors are optional, and the keywords are: normal, selected, disabled, marked,
+markselect, errors, input, inputmark, inputunchanged, commandlinemark,
+reverse, gauge, header, inputhistory, commandhistory. Button bar colors are:
+bbarhotkey, bbarbutton. Status bar color: statusbar. Menu colors are: menunormal,
+menusel, menuhot, menuhotsel, menuinactive. Dialog colors are: dnormal, dfocus,
+dhotnormal, dhotfocus, dtitle. Error dialog colors are: errdfocus, errdhotnormal,
+errdhotfocus, errdtitle.  Help colors are: helpnormal, helpitalic, helpbold,
+helplink, helpslink, helptitle.  Viewer colors are: viewnormal, viewbold,
+viewunderline, viewselected. Editor colors are: editnormal, editbold, editmarked,
+editwhitespace, editlinestate. Popup menu colors are: pmenunormal, pmenusel,
+pmenutitle.
+.PP
+.I header
+determines the color of panel header, the line that contains column titles
+and sort mode indicator.
+.PP
+.I input
+determines the color of input lines used in query dialogs.
+.PP
+.I gauge
+determines the color of the filled part of the progress bar (gauge),
+which is used to show the user the progress of file operations, such as
+copying.
+.PP
+.I disabled
+determines the color of the widget that cannot be selected.
+.PP
+The dialog boxes use the following colors:
+.I dnormal
+is used for the normal text,
+.I dfocus
+is the color used for the currently selected component,
+.I dhotnormal
+is the color used to differentiate the hotkey color in normal
+components, whereas the
+.I dhotfocus
+color is used for the highlighted color in the currently selected
+component.
+.PP
+Menus use the same scheme but uses the menunormal, menusel, menuhot, menuhotsel
+and menuinactive tags instead.
+.PP
+Help uses the following colors:
+.I helpnormal
+is used for normal text,
+.I helpitalic
+is used for text which is emphasized in italic in the manual page,
+.I helpbold
+is used for text which is emphasized in bold in the manual page,
+.I helplink
+is used for not selected hyperlinks and
+.I helpslink
+is used for selected hyperlink.
+.PP
+Popup menu uses following colors:
+.I pmenunormal
+is used for non\-selected menu items and as a main color of popup menu window,
+.I pmenusel
+is used for selected menu item,
+.I pmenutitle
+is used for popup menu title.
+.PP
+The possible colors are: black, gray, red, brightred, green,
+brightgreen, brown, yellow, blue, brightblue, magenta, brightmagenta,
+cyan, brightcyan, lightgray and white. And there is a special keyword
+for transparent background. It is 'default'. The 'default' can only be
+used for background color. Another special keyword "base" means mc's main
+colors.  When 256 colors are available, they can be specified either as
+color16 to color255, or as rgb000 to rgb555 and gray0 to gray23. Example:
+.PP
+.nf
+[Colors]
+base_color=normal=white,default:marked=magenta,default
+.fi
+.PP
+Attributes can be any of bold, italic, underline, reverse and blink, appended by a
+plus sign if more than one are desired.  The special word "none" means no

+These variables may be set in your ~/.config/mc/ini file:
+.TP
+.I clear_before_exec
+By default, Midnight Commander clears the screen before executing a

+bottom of the screen, edit your ~/.config/mc/ini file and change the value of
+the field clear_before_exec to 0.
+.TP
+.I confirm_view_dir
+If you press F3 on a directory, normally MC enters that directory.  If
+this flag is set to 1, then MC will ask for confirmation before changing
+the directory if you have files tagged.
+.TP
+.I ftpfs_retry_seconds
+This value is the number of seconds Midnight Commander will wait
+before attempting to reconnect to an FTP server that has denied the
+login.  If the value is zero, the login will no be retried.
+.TP
+.I max_dirt_limit
+Specifies how many screen updates can be skipped at most in the internal
+file viewer.  Normally this value is not significant, because the code
+automatically adjusts the number of updates to skip according to the
+rate of incoming keystrokes.  However, on very slow machines or
+terminals with a fast keyboard auto repeat, a big value can make screen
+updates too jumpy.
+.IP
+It seems that setting max_dirt_limit to 10 causes the best behavior,
+and that is the default value.
+.TP
+.I mouse_move_pages_viewer
+Controls if scrolling with the mouse is done by pages or line by line
+on the internal file viewer.
+.TP
+.I only_leading_plus_minus
+Allow special treatment for '+', '\-', '*' in the command line (select,
+unselect, reverse selection) only if the command line is empty.  You
+don't need to quote those characters in the middle of the command line.
+On the other hand, you cannot use them to change selection when the
+command line is not empty.
+.TP
+.I alternate_plus_minus
+If true, use '+', '\-', '\\' and '*' keys normally. For select/unselect,
+use 'Alt\-+', 'Alt\--' and 'Alt\-*'.
+.TP
+.I show_output_starts_shell
+This variable only works if you are not using the subshell support.
+When you use the C\-o keystroke to go back to the user screen, if this
+one is set, you will get a fresh shell.  Otherwise, pressing any key
+will bring you back to Midnight Commander.
+.TP

+Change the time format used to display dates less than 6 months from
+now.
+See strftime or date man page for the format specification. If this
+option is absent, default timeformat is used.

+top line unless it is already on the top line, in this case it will go
+to the first file in the panel.
+.IP
+The end key has a similar behavior: Go down to the middle line, if over
+it; else go to the bottom line unless you already are at the bottom
+line, in such case it will move the selection to the last file name in
+the panel.
+.TP
+.I use_file_to_guess_type
+If this variable is on (the default) it will spawn the file command to
+match the file types listed on the
+.\"LINK2"
+mc.ext.ini file\&.
+.\"Edit Extension File"
+.TP
+.I xtree_mode
+If this variable is on (default is off) when you browse the file system
+on a Tree panel, it will automatically reload the other panel with the
+contents of the selected directory.
+.TP
+.I fish_directory_timeout
+This variable holds the lifetime of a directory cache entry in seconds. The
+default value is 900 seconds.
+.TP
+.I clipboard_store
+This variable contains path (with options) to the external clipboard
+utility like 'xclip' to read text into X selection from file.
+For example:
+.PP
+.nf
+clipboard_store=xclip \-i
+.fi
+.TP
+.I clipboard_paste
+This variable contains path (with options) to the external clipboard
+utility like 'xclip' to print the selection to standard out.
+For example:
+.PP
+.nf
+clipboard_paste=xclip \-o
+.fi
+.TP
+.I autodetect_codeset
+This option allows use the `enca' command to autodetect codeset of text files
+in internal viewer and editor. List of valid values can be obtain by the
+`enca \-\-list languages | cut \-d : \-f1' command. Option must be located
+in the [Misc] section.
+.PP
+For example:
+.PP
+.nf
+autodetect_codeset=russian

+.\"NODE "Parameters for external editor or viewer"
+.SH "Parameters for external editor or viewer"
+Midnight Commander provides a way for specify an options for external editors
+and viewers. Midnight Commander tries to search the
+"[External editor or viewer parameters]" section in the system initialization file
+(the mc.lib file located in Midnight Commander's library directory)
+and then in the ~/.config/mc/ini file. The option name should be equal to the name
+(full pathname) of external editor or viewer. The option value can contain following
+variables:
+.TP
+.I %filename
+The filename to edit/view.
+.TP
+.I %lineno
+The start line in the opening file.
+.PP
+For example:
+.PP
+.nf
+[External editor or viewer parameters]
+    vi=%filename +%lineno
+    joe=%filename +%lineno
+    more=%filename +%lineno
+.fi
+.PP
+Start line is passed to the external editor/viewer only if it is called from the
+.\"LINK2"
+Find file
+.\"Find File"
+results window.
+.PP
+If external editor/viewer is launched via F4/F3 keys, MC hopes that program
+(at least "joe", but probably others too) has an own feature that by default
+opens the file where it was last open. MC doesn't prevent external editor/viewer
+to save and restore position in opened files.
+.\"NODE "Terminal databases"
+.SH "Terminal databases"
+Midnight Commander provides a way to fix your system terminal
+database without requiring root privileges. Midnight Commander
+searches in the system initialization file (the mc.lib file located in
+Midnight Commander's library directory) and in the 
+~/.config/mc/ini file for the section 
+"terminal:your\-terminal\-name" and then for the section
+"terminal:general", each line of the section contains a key symbol that
+you want to define, followed by an equal sign and the definition for the
+key.  You can use the special \\e form to represent the escape character
+and the ^x to represent the control\-x character.
+.PP
+The possible key symbols are:
+.PP
+.nf
+f0 to f20     Function keys f0\-f20
+bs            backspace
+home          home key
+end           end key
+up            up arrow key
+down          down arrow key
+left          left arrow key
+right         right arrow key
+pgdn          page down key
+pgup          page up key
+insert        the insert character
+delete        the delete character
+complete      to do completion
+.fi
+.PP
+For example, to define the key insert to be the Escape + [ + O + p, you
+set this in the ini file:
+.PP
+.nf
+insert=\\e[Op
+.fi
+
+.PP
+Also now you can use
+.I extended learn keys.
+For example:
+
+.nf
+    ctrl\-alt\-right=\\e[[1;6C
+    ctrl\-alt\-left=\\e[[1;6D
+.fi
+
+.PP
+This means that ctrl+alt+left sends a \\e[[1;6D escape sequence
+and therefore Midnight Commander interprets "\\e[[1;6D" as C\-Alt\-Left.
+
+.PP
+The
+.I complete
+key symbol represents the escape sequences used to invoke the completion
+process, this is invoked with Alt\-tab, but you can define other keys to do
+the same work (on those keyboard with tons of nice and unused keys
+everywhere).
