+
+Terminal information *terminal-info*
+
+Vim uses information about the terminal you are using to fill the screen and
+recognize what keys you hit. If this information is not correct, the screen
+may be messed up or keys may not be recognized. The actions which have to be
+performed on the screen are accomplished by outputting a string of
+characters. Special keys produce a string of characters. These strings are
+stored in the terminal options, see |terminal-options|.
+
+NOTE: Most of this is not used when running the |GUI|.
+
+1. Startup |startup-terminal|
+2. Terminal options |terminal-options|
+3. Window size |window-size|
+4. Slow and fast terminals |slow-fast-terminal|
+5. Using the mouse |mouse-using|
+
+==============================================================================
+1. Startup *startup-terminal*
+
+When Vim is started a default terminal type is assumed. For the Amiga this is
+a standard CLI window, for MS-Windows the pc terminal, for Unix an ansi
+terminal. A few other terminal types are always available, see below
+|builtin-terms|.
+
+You can give the terminal name with the '-T' Vim argument. If it is not given
+Vim will try to get the name from the TERM environment variable.
+
+ *termcap* *terminfo* *E557* *E558* *E559*
+On Unix the terminfo database or termcap file is used. This is referred to as
+"termcap" in all the documentation. At compile time, when running configure,
+the choice whether to use terminfo or termcap is done automatically. When
+running Vim the output of ":version" will show |+terminfo| if terminfo is
+used. Also see |xterm-screens|.
+
+On non-Unix systems a termcap is only available if Vim was compiled with
+TERMCAP defined.
+
+ *builtin-terms* *builtin_terms*
+A number of builtin terminals are available. Since patch 9.0.0280 there is no
+difference between Vim versions. You can see a list of available builtin
+terminals in the error message you get for `:set term=xxx` (when not running
+the GUI). Also see |++builtin_terms|.
+
+If the termcap code is included Vim will try to get the strings for the
+terminal you are using from the termcap file and the builtin termcaps. Both
+are always used, if an entry for the terminal you are using is present. Which
+one is used first depends on the 'ttybuiltin' option:
+
+'ttybuiltin' on 1: builtin termcap 2: external termcap
+'ttybuiltin' off 1: external termcap 2: builtin termcap
+
+If an option is missing in one of them, it will be obtained from the other
+one. If an option is present in both, the one first encountered is used.
+
+Which external termcap file is used varies from system to system and may
+depend on the environment variables "TERMCAP" and "TERMPATH". See "man
+tgetent".
+
+Settings depending on terminal *term-dependent-settings*
+
+If you want to set options or mappings, depending on the terminal name, you
+can do this best in your .vimrc. Example: >
+
+ if &term == "xterm"
+ ... xterm maps and settings ...
+ elseif &term =~ "vt10."
+ ... vt100, vt102 maps and settings ...
+ endif
+<
+ *raw-terminal-mode*
+For normal editing the terminal will be put into "raw" mode. The strings
+defined with 't_ti', 't_TI' and 't_ks' will be sent to the terminal. Normally
+this puts the terminal in a state where the termcap codes are valid and
+activates the cursor and function keys.
+When Vim exits the terminal will be put back into the mode it was before Vim
+started. The strings defined with 't_te', 't_TE' and 't_ke' will be sent to
+the terminal. On the Amiga, with commands that execute an external command
+(e.g., "!!"), the terminal will be put into Normal mode for a moment. This
+means that you can stop the output to the screen by hitting a printing key.
+Output resumes when you hit <BS>.
+
+Note: When 't_ti' is not empty, Vim assumes that it causes switching to the
+alternate screen. This may slightly change what happens when executing a
+shell command or exiting Vim. To avoid this use 't_TI' and 't_TE' (but make
+sure to add to them, not overwrite).
+
+Vim will try to detect what keyboard protocol the terminal is using with the
+'t_RK' termcap entry. This is sent after 't_TI', but only when there is no
+work to do (no typeahead and no pending commands). That is to avoid the
+response to end up in a shell command or arrive after Vim exits.
+
+ *xterm-bracketed-paste*
+When the 't_BE' option is set then 't_BE' will be sent to the
+terminal when entering "raw" mode and 't_BD' when leaving "raw" mode. The
+terminal is then expected to put 't_PS' before pasted text and 't_PE' after
+pasted text. This way Vim can separate text that is pasted from characters
+that are typed. The pasted text is handled like when the middle mouse button
+is used, it is inserted literally and not interpreted as commands.
+
+When the cursor is in the first column, the pasted text will be inserted
+before it. Otherwise the pasted text is appended after the cursor position.
+This means one cannot paste after the first column. Unfortunately Vim does
+not have a way to tell where the mouse pointer was.
+
+Note that in some situations Vim will not recognize the bracketed paste and
+you will get the raw text. In other situations Vim will only get the first
+pasted character and drop the rest, e.g. when using the "r" command. If you
+have a problem with this, disable bracketed paste by putting this in your
+.vimrc: >
+ set t_BE=
+If this is done while Vim is running the 't_BD' will be sent to the terminal
+to disable bracketed paste.
+
+If |t_PS| or |t_PE| is not set, then |t_BE| will not be used. This is to make
+sure that bracketed paste is not enabled when the escape codes surrounding
+pasted text cannot be recognized.
+
+If your terminal supports bracketed paste, but the options are not set
+automatically, you can try using something like this: >
+
+ if &term =~ "screen"
+ let &t_BE = "\e[?2004h"
+ let &t_BD = "\e[?2004l"
+ exec "set t_PS=\e[200~"
+ exec "set t_PE=\e[201~"
+ endif
+
+The terminfo entries "BE", "BD", "PS" and "PE" were added in ncurses version
+6.4, early 2023, for some terminals. If you have this version then you may
+not have to manually configure your terminal.
+
+ *tmux-integration*
+If you experience issues when running Vim inside tmux, here are a few hints.
+You can comment-out parts if something doesn't work (it may depend on the
+terminal that tmux is running in): >
+
+ if !has('gui_running') && &term =~ '^\%(screen\|tmux\)'
+ " Better mouse support, see :help 'ttymouse'
+ set ttymouse=sgr
+
+ " Enable true colors, see :help xterm-true-color
+ let &termguicolors = v:true
+ let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
+ let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"
+
+ " Enable bracketed paste mode, see :help xterm-bracketed-paste
+ let &t_BE = "\<Esc>[?2004h"
+ let &t_BD = "\<Esc>[?2004l"
+ let &t_PS = "\<Esc>[200~"
+ let &t_PE = "\<Esc>[201~"
+
+ " Enable focus event tracking, see :help xterm-focus-event
+ let &t_fe = "\<Esc>[?1004h"
+ let &t_fd = "\<Esc>[?1004l"
+ execute "set <FocusGained>=\<Esc>[I"
+ execute "set <FocusLost>=\<Esc>[O"
+
+ " Enable modified arrow keys, see :help arrow_modifiers
+ execute "silent! set <xUp>=\<Esc>[@;*A"
+ execute "silent! set <xDown>=\<Esc>[@;*B"
+ execute "silent! set <xRight>=\<Esc>[@;*C"
+ execute "silent! set <xLeft>=\<Esc>[@;*D"
+ endif
+<
+ *cs7-problem*
+Note: If the terminal settings are changed after running Vim, you might have
+an illegal combination of settings. This has been reported on Solaris 2.5
+with "stty cs8 parenb", which is restored as "stty cs7 parenb". Use
+"stty cs8 -parenb -istrip" instead, this is restored correctly.
+
+Some termcap entries are wrong in the sense that after sending 't_ks' the
+cursor keys send codes different from the codes defined in the termcap. To
+avoid this you can set 't_ks' (and 't_ke') to empty strings. This must be
+done during initialization (see |initialization|), otherwise it's too late.
+
+Some termcap entries assume that the highest bit is always reset. For
+example: The cursor-up entry for the Amiga could be ":ku=\E[A:". But the
+Amiga really sends "\233A". This works fine if the highest bit is reset,
+e.g., when using an Amiga over a serial line. If the cursor keys don't work,
+try the entry ":ku=\233A:".
+
+Some termcap entries have the entry ":ku=\E[A:". But the Amiga really sends
+"\233A". On output "\E[" and "\233" are often equivalent, on input they
+aren't. You will have to change the termcap entry, or change the key code with
+the :set command to fix this.
+
+Many cursor key codes start with an <Esc>. Vim must find out if this is a
+single hit of the <Esc> key or the start of a cursor key sequence. It waits
+for a next character to arrive. If it does not arrive within one second a
+single <Esc> is assumed. On very slow systems this may fail, causing cursor
+keys not to work sometimes. If you discover this problem reset the 'timeout'
+option. Vim will wait for the next character to arrive after an <Esc>. If
+you want to enter a single <Esc> you must type it twice. Resetting the
+'esckeys' option avoids this problem in Insert mode, but you lose the
+possibility to use cursor and function keys in Insert mode.
+
+On the Amiga the recognition of window resizing is activated only when the
+terminal name is "amiga" or "builtin_amiga".
+
+Some terminals have confusing codes for the cursor keys. The televideo 925 is
+such a terminal. It sends a CTRL-H for cursor-left. This would make it
+impossible to distinguish a backspace and cursor-left. To avoid this problem
+CTRL-H is never recognized as cursor-left.
+
+ *vt100-cursor-keys* *xterm-cursor-keys*
+Other terminals (e.g., vt100 and xterm) have cursor keys that send <Esc>OA,
+<Esc>OB, etc. Unfortunately these are valid commands in insert mode: Stop
+insert, Open a new line above the new one, start inserting 'A', 'B', etc.
+Instead of performing these commands Vim will erroneously recognize this typed
+key sequence as a cursor key movement. To avoid this and make Vim do what you
+want in either case you could use these settings: >
+ :set notimeout " don't timeout on mappings
+ :set ttimeout " do timeout on terminal key codes
+ :set timeoutlen=100 " timeout after 100 msec
+This requires the key-codes to be sent within 100 msec in order to recognize
+them as a cursor key. When you type you normally are not that fast, so they
+are recognized as individual typed commands, even though Vim receives the same
+sequence of bytes.
+
+ *vt100-function-keys* *xterm-function-keys*
+An xterm can send function keys F1 to F4 in two modes: vt100 compatible or
+not. Because Vim may not know what the xterm is sending, both types of keys
+are recognized. The same happens for the <Home> and <End> keys.
+ normal vt100 ~
+ <F1> t_k1 <Esc>[11~ <xF1> <Esc>OP *<xF1>-xterm*
+ <F2> t_k2 <Esc>[12~ <xF2> <Esc>OQ *<xF2>-xterm*
+ <F3> t_k3 <Esc>[13~ <xF3> <Esc>OR *<xF3>-xterm*
+ <F4> t_k4 <Esc>[14~ <xF4> <Esc>OS *<xF4>-xterm*
+ <Home> t_kh <Esc>[7~ <xHome> <Esc>OH *<xHome>-xterm*
+ <End> t_@7 <Esc>[4~ <xEnd> <Esc>OF *<xEnd>-xterm*
+
+When Vim starts, <xF1> is mapped to <F1>, <xF2> to <F2> etc. This means that
+by default both codes do the same thing. If you make a mapping for <xF2>,
+because your terminal does have two keys, the default mapping is overwritten,
+thus you can use the <F2> and <xF2> keys for something different.
+
+ *xterm-shifted-keys*
+Newer versions of xterm support shifted function keys and special keys. Vim
+recognizes most of them. Use ":set termcap" to check which are supported and
+what the codes are. Mostly these are not in a termcap, they are only
+supported by the builtin_xterm termcap.
+
+ *xterm-modifier-keys*
+Newer versions of xterm support Alt and Ctrl for most function keys. To avoid
+having to add all combinations of Alt, Ctrl and Shift for every key a special
+sequence is recognized at the end of a termcap entry: ";*X". The "X" can be
+any character, often '~' is used. The ";*" stands for an optional modifier
+argument. ";2" is Shift, ";3" is Alt, ";5" is Ctrl and ";9" is Meta (when
+it's different from Alt). They can be combined. Examples: >
+ :set <F8>=^[[19;*~
+ :set <Home>=^[[1;*H
+Another speciality about these codes is that they are not overwritten by
+another code. That is to avoid that the codes obtained from xterm directly
+|t_RV| overwrite them.
+
+Another special value is a termcap entry ending in "@;*X". This is for cursor
+keys, which either use "CSI X" or "CSI 1 ; modifier X". Thus the "@"
+stands for either "1" if a modifier follows, or nothing.
+ *arrow_modifiers*
+Several terminal emulators (alacritty, gnome, konsole, etc.) send special
+codes for keys with modifiers, but these do not have an entry in the
+termcap/terminfo database. You can make them work by adding a few lines in
+your vimrc. For example, to make the Control modifier work with arrow keys
+for the gnome terminal: >
+ if &term =~ 'gnome'
+ execute "set <xUp>=\<Esc>[@;*A"
+ execute "set <xDown>=\<Esc>[@;*B"
+ execute "set <xRight>=\<Esc>[@;*C"
+ execute "set <xLeft>=\<Esc>[@;*D"
+ endif
+< *xterm-scroll-region*
+The default termcap entry for xterm on Sun and other platforms does not
+contain the entry for scroll regions. Add ":cs=\E[%i%d;%dr:" to the xterm
+entry in /etc/termcap and everything should work.
+
+ *xterm-end-home-keys*
+On some systems (at least on FreeBSD with XFree86 3.1.2) the codes that the
+<End> and <Home> keys send contain a <Nul> character. To make these keys send
+the proper key code, add these lines to your ~/.Xdefaults file:
+
+*VT100.Translations: #override \n\
+ <Key>Home: string("0x1b") string("[7~") \n\
+ <Key>End: string("0x1b") string("[8~")
+
+ *xterm-8bit* *xterm-8-bit*
+Xterm can be run in a mode where it uses 8-bit escape sequences. The CSI code
+is used instead of <Esc>[. The advantage is that an <Esc> can quickly be
+recognized in Insert mode, because it can't be confused with the start of a
+special key.
+For the builtin termcap entries, Vim checks if the 'term' option contains
+"8bit" anywhere. It then uses 8-bit characters for the termcap entries, the
+mouse and a few other things. You would normally set $TERM in your shell to
+"xterm-8bit" and Vim picks this up and adjusts to the 8-bit setting
+automatically.
+When Vim receives a response to the |t_RV| (request version) sequence and it
+starts with CSI, it assumes that the terminal is in 8-bit mode and will
+convert all key sequences to their 8-bit variants.
+
+ *xterm-terminfo-entries*
+For some time the terminfo entries were insufficient to describe all the
+features tht Vim can use. The builtin xterm termcap entries did have these,
+with the result that several terminals that were similar enough to xterm took
+advantage of these by prefixing "xterm-" to the terminal name in $TERM.
+
+This leads to problems, because quite often these terminals are not 100%
+compatible with xterm. At the start of 2023 several entries have been added
+to the terminfo database to make it possible to use these features without
+using the "xterm" workaround. These are the relevant entries (so far):
+
+ name xterm value description ~
+ RV "\033[>c" Request version |t_RV|
+
+ BE "\033[?2004h" enable bracketed paste mode |t_BE|
+ BD "\033[?2004l" disable bracketed paste mode |t_BD|
+ PS "\033[200~" pasted text start |t_PS|
+ PE "\033[201~" pasted text end |t_PE|
+
+ XM "\033[?1006;1004;1000%?%p1%{1}%=%th%el%;"
+ mouse enable / disable |t_XM|
+
+The "XM" entry includes "1006" to enable SGR style mouse reporting. This
+supports columns above 223. It also includes "1004" which enables focus
+reporting. The t_fe and t_fd entries can be left empty (they don't have
+entries in terminfo/termcap anyway).
+
+ *xterm-kitty* *kitty-terminal*
+The Kitty terminal is a special case. Mainly because it works differently
+from most other terminals, but also because, instead of trying the fit in and
+make it behave like other terminals by default, it dictates how applications
+need to work when using Kitty. This makes it very difficult for Vim to work
+in a Kitty terminal. Some exceptions have been hard coded, but it is not at
+all nice to have to make exceptions for one specific terminal.
+
+One of the problems is that the value for $TERM is set to "xterm-kitty". For
+Vim this is an indication that the terminal is xterm-compatible and the
+builtin xterm termcap entries should be used. Many other terminals depend on
+this. However, Kitty is not fully xterm compatible. The author suggested to
+ignore the "xterm-" prefix and use the terminfo entry anyway, so that is what
+happens now, the builtin xterm termcap entries are not used. However, the
+t_RV is set, otherwise other things would not work, such as automatically
+setting 'ttymouse' to "sgr" (at least until |t_XM| is being used for this).
+
+It is not clear why kitty sets $TERM to "xterm-kitty", the terminal isn't
+really xterm compatible. "kitty" would be more appropriate, but a terminfo
+entry with that name is not widespread.
+
+Note that using the kitty keyboard protocol is a separate feature, see
+|kitty-keyboard-protocol|.
+
+
+==============================================================================
+2. Terminal options *terminal-options* *termcap-options* *E436*
+
+The terminal options can be set just like normal options. But they are not
+shown with the ":set all" command. Instead use ":set termcap".
+
+It is always possible to change individual strings by setting the
+appropriate option. For example: >
+ :set t_ce=^V^[[K (CTRL-V, <Esc>, [, K)
+
+The options are listed below. The associated termcap code is always equal to
+the last two characters of the option name. Only one termcap code is
+required: Cursor motion, 't_cm'.
+
+The options 't_da', 't_db', 't_ms', 't_xs', 't_xn' represent flags in the
+termcap. When the termcap flag is present, the option will be set to "y".
+But any non-empty string means that the flag is set. An empty string means
+that the flag is not set. 't_CS' works like this too, but it isn't a termcap
+flag.

+ 6 vertical bar cursor
+
+t_RS is sent only if the response to t_RV has been received. It is not used
+on Mac OS when Terminal.app could be recognized from the termresponse.
+
+ *mouse-reporting*
+Many terminals can report mouse clicks and some can report mouse movement and
+dragging. Vim needs to know what codes are being used for this.
+
+The "XM" terminfo/termcap entry is used for this. Vim also has the 'ttymouse'
+option to specify the mouse protocol being used. See the option for the
+possible values.
+
+If Vim can read the "XM" terminfo/termcap entry then it will be used for
+enabling and disabling the mouse reporting. If it is missing, then the value
+from 'ttymouse' is used to decide how to do this.
+
+If the "XM" entry exists and the first number is "1006" then 'ttymouse' will
+be set to "sgr", unless it was already set earlier.

+
+Note about t_so and t_mr: When the termcap entry "so" is not present the
+entry for "mr" is used. And vice versa. The same is done for "se" and "me".
+If your terminal supports both inversion and standout mode, you can see two
+different modes. If your terminal supports only one of the modes, both will
+look the same.
+
+ *keypad-comma*
+The keypad keys, when they are not mapped, behave like the equivalent normal
+key. There is one exception: if you have a comma on the keypad instead of a
+decimal point, Vim will use a dot anyway. Use these mappings to fix that: >
+ :noremap <kPoint> ,
+ :noremap! <kPoint> ,
+< *xterm-codes*
+There is a special trick to obtain the key codes which currently only works
+for xterm. When |t_RV| is defined and a response is received which indicates
+an xterm with patchlevel 141 or higher, Vim uses special escape sequences to
+request the key codes directly from the xterm. The responses are used to
+adjust the various t_ codes. This avoids the problem that the xterm can
+produce different codes, depending on the mode it is in (8-bit, VT102,
+VT220, etc.). The result is that codes like <xF1> are no longer needed.
+
+One of the codes that can change is 't_Co', the number of colors. This will
+trigger a redraw. If this is a problem, reset the 'xtermcodes' option as
+early as possible: >
+ set noxtermcodes
+
+Note: Requesting the key codes is only done on startup. If the xterm options
+are changed after Vim has started, the escape sequences may not be recognized
+anymore.
+
+ *xterm-true-color*
+Vim supports using true colors in the terminal (taken from |highlight-guifg|
+and |highlight-guibg|), given that the terminal supports this. To make this
+work the 'termguicolors' option needs to be set.
+See https://github.com/termstandard/colors for a list of terminals that
+support true colors.
+
+For telling the terminal what RGB color to use the |t_8f| and |t_8b| termcap
+entries are used. These are set by default to values that work for most
+terminals. If that does not work for your terminal you can set them manually.
+The default values are set like this: >
+ let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
+ let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"
+
+Some terminals accept the same sequences, but with all semicolons replaced by
+colons (this is actually more compatible, but less widely supported): >
+ let &t_8f = "\<Esc>[38:2:%lu:%lu:%lum"
+ let &t_8b = "\<Esc>[48:2:%lu:%lu:%lum"
+
+These options contain printf strings, with |printf()| (actually, its C
+equivalent hence `l` modifier) invoked with the t_ option value and three
+unsigned long integers that may have any value between 0 and 255 (inclusive)
+representing red, green and blue colors respectively.
+
+ *xterm-resize*
+Window resizing with xterm only works if the allowWindowOps resource is
+enabled. On some systems and versions of xterm it's disabled by default
+because someone thought it would be a security issue. It's not clear if this
+is actually the case.
+
+To overrule the default, put this line in your ~/.Xdefaults or
+~/.Xresources:
+>
+ XTerm*allowWindowOps: true
+
+And run "xrdb -merge .Xresources" to make it effective. You can check the
+value with the context menu (right mouse button while CTRL key is pressed),
+there should be a tick at allow-window-ops.
+
+ *xterm-focus-event*
+Some terminals including xterm support the focus event tracking feature.
+If this feature is enabled by the 't_fe' sequence, special key sequences are
+sent from the terminal to Vim every time the terminal gains or loses focus.
+Vim fires focus events (|FocusGained|/|FocusLost|) by handling them accordingly.
+Focus event tracking is disabled by a 't_fd' sequence when exiting "raw" mode.
+If you would like to disable this feature, add the following to your .vimrc:
+ `set t_fd=`
+ `set t_fe=`
+If your terminal does support this but Vim does not recognize the terminal,
+you may have to set the options yourself: >
+ let &t_fe = "\<Esc>[?1004h"
+ let &t_fd = "\<Esc>[?1004l"
+ execute "set <FocusGained>=\<Esc>[I"
+ execute "set <FocusLost>=\<Esc>[O"
+If this causes garbage to show when Vim starts up then it doesn't work.
+
+ *termcap-colors*
+Note about colors: The 't_Co' option tells Vim the number of colors available.
+When it is non-zero, the 't_AB' and 't_AF' options are used to set the color.
+If one of these is not available, 't_Sb' and 't_Sf' are used. 't_me' is used
+to reset to the default colors. Also see 'termguicolors'.
+When the GUI is running 't_Co' is set to 16777216.
+
+ *termcap-cursor-shape* *termcap-cursor-color*
+When Vim enters Insert mode the 't_SI' escape sequence is sent. When Vim
+enters Replace mode the 't_SR' escape sequence is sent if it is set, otherwise
+'t_SI' is sent. When leaving Insert mode or Replace mode 't_EI' is used.
+Note: When 't_EI' is not set then 't_SI' and 't_SR' will not be sent. And
+when 't_SI' or 't_SR' is not set then 't_EI' is sent only once.
+
+This can be used to change the shape or color of the cursor in Insert or
+Replace mode. These are not standard termcap/terminfo entries, you need to set
+them yourself.
+Example for an xterm, this changes the color of the cursor: >
+ if &term =~ "xterm"
+ let &t_SI = "\<Esc>]12;purple\x7"
+ let &t_SR = "\<Esc>]12;red\x7"
+ let &t_EI = "\<Esc>]12;blue\x7"
+ endif
+NOTE: When Vim exits the shape for Normal mode will remain. The shape from
+before Vim started will not be restored.
+
+For Windows Terminal you can use something like this: >
+ " Note: This should be set after `set termguicolors` or `set t_Co=256`.
+ if &term =~ 'xterm' || &term == 'win32'
+ " Use DECSCUSR escape sequences
+ let &t_SI = "\e[5 q" " blink bar
+ let &t_SR = "\e[3 q" " blink underline
+ let &t_EI = "\e[1 q" " blink block
+ let &t_ti ..= "\e[1 q" " blink block
+ let &t_te ..= "\e[0 q" " default (depends on terminal, normally blink block)
+ endif
+
+{not available when compiled without the |+cursorshape| feature}
+
+ *termcap-title*
+The 't_ts' and 't_fs' options are used to set the window title if the terminal
+allows title setting via sending strings. They are sent before and after the
+title string, respectively. Similar 't_IS' and 't_IE' are used to set the
+icon text. These are Vim-internal extensions of the Unix termcap, so they
+cannot be obtained from an external termcap. However, the builtin termcap
+contains suitable entries for xterm and iris-ansi, so you don't need to set
+them here.
+ *hpterm*
+If inversion or other highlighting does not work correctly, try setting the
+'t_xs' option to a non-empty string. This makes the 't_ce' code be used to
+remove highlighting from a line. This is required for "hpterm". Setting the
+'weirdinvert' option has the same effect as making 't_xs' non-empty, and vice
+versa.
+
+ *scroll-region*
+Some termcaps do not include an entry for "cs" (scroll region), although the
+terminal does support it. For example: xterm on a Sun. You can use the
+builtin_xterm or define t_cs yourself. For example: >
+ :set t_cs=^V^[[%i%d;%dr
+Where ^V is CTRL-V and ^[ is <Esc>.
+
+The vertical scroll region t_CV is not a standard termcap code. Vim uses it
+internally in the GUI. But it can also be defined for a terminal, if you can
+find one that supports it. The two arguments are the left and right column of
+the region which to restrict the scrolling to. Just like t_cs defines the top
+and bottom lines. Defining t_CV will make scrolling in vertically split
+windows a lot faster. Don't set t_CV when t_da or t_db is set (text isn't
+cleared when scrolling).
+
+Unfortunately it is not possible to deduce from the termcap how cursor
+positioning should be done when using a scrolling region: Relative to the
+beginning of the screen or relative to the beginning of the scrolling region.
+Most terminals use the first method. The 't_CS' option should be set to any
+string when cursor positioning is relative to the start of the scrolling
+region. It should be set to an empty string otherwise.
+
+Note for xterm users: The shifted cursor keys normally don't work. You can
+ make them work with the xmodmap command and some mappings in Vim.
+
+ Give these commands in the xterm:
+ xmodmap -e "keysym Up = Up F13"
+ xmodmap -e "keysym Down = Down F16"
+ xmodmap -e "keysym Left = Left F18"
+ xmodmap -e "keysym Right = Right F19"
+
+ And use these mappings in Vim:
+ :map <t_F3> <S-Up>
+ :map! <t_F3> <S-Up>
+ :map <t_F6> <S-Down>
+ :map! <t_F6> <S-Down>
+ :map <t_F8> <S-Left>
+ :map! <t_F8> <S-Left>
+ :map <t_F9> <S-Right>
+ :map! <t_F9> <S-Right>
+
+Instead of, say, <S-Up> you can use any other command that you want to use the
+shift-cursor-up key for. (Note: To help people that have a Sun keyboard with
+left side keys F14 is not used because it is confused with the undo key; F15
+is not used, because it does a window-to-front; F17 is not used, because it
+closes the window. On other systems you can probably use them.)
+
+==============================================================================
+3. Window size *window-size*
+
+[This is about the size of the whole window Vim is using, not a window that is
+created with the ":split" command.]
+
+If you are running Vim on an Amiga and the terminal name is "amiga" or
+"builtin_amiga", the amiga-specific window resizing will be enabled. On Unix
+systems three methods are tried to get the window size:
+
+- an ioctl call (TIOCGSIZE or TIOCGWINSZ, depends on your system)
+- the environment variables "LINES" and "COLUMNS"
+- from the termcap entries "li" and "co"
+
+If everything fails a default size of 24 lines and 80 columns is assumed. If
+a window-resize signal is received the size will be set again. If the window
+size is wrong you can use the 'lines' and 'columns' options to set the
+correct values.
+
+One command can be used to set the screen size:
+ *:mod* *:mode* *E359*
+:mod[e] [mode]
+
+Without argument this only detects the screen size and redraws the screen.
+[mode] was used on MS-DOS, but it doesn't work anymore. In |Vim9| this
+command is not supported.
+
+==============================================================================
+4. Slow and fast terminals *slow-fast-terminal*
+ *slow-terminal*
+
+If you have a fast terminal you may like to set the 'ruler' option. The
+cursor position is shown in the status line. If you are using horizontal
+scrolling ('wrap' option off) consider setting 'sidescroll' to a small
+number.
+
+If you have a slow terminal you may want to reset the 'showcmd' option.
+The command characters will not be shown in the status line. If the terminal
+scrolls very slowly, set the 'scrolljump' to 5 or so. If the cursor is moved
+off the screen (e.g., with "j") Vim will scroll 5 lines at a time. Another
+possibility is to reduce the number of lines that Vim uses with the command
+"z{height}<CR>".
+
+If the characters from the terminal are arriving with more than 1 second
+between them you might want to set the 'timeout' and/or 'ttimeout' option.
+See the "Options" chapter |options|.
+
+If your terminal does not support a scrolling region, but it does support
+insert/delete line commands, scrolling with multiple windows may make the
+lines jump up and down. This would happen if the 'ttyfast' option has been
+reset. Check that with: >
+ verbose set ttyfast?
+
+If your terminal scrolls very slowly, but redrawing is not slow, set the
+'ttyscroll' option to a small number, e.g., 3. This will make Vim redraw the
+screen instead of scrolling, when there are more than 3 lines to be scrolled.
+
+If you are using a color terminal that is slow, use this command: >
+ hi NonText cterm=NONE ctermfg=NONE
+This avoids that spaces are sent when they have different attributes. On most
+terminals you can't see this anyway.
+
+If you are using Vim over a slow serial line, you might want to try running
+Vim inside the "screen" program. Screen will optimize the terminal I/O quite
+a bit.
+
+If you are testing termcap options, but you cannot see what is happening, you
+might want to set the 'writedelay' option. When non-zero, one character is
+sent to the terminal at a time. This makes the screen updating a lot slower,
+making it possible to see what is happening.
+
+==============================================================================
+5. Using the mouse *mouse-using*
+
+This section is about using the mouse on a terminal or a terminal window. How
+to use the mouse in a GUI window is explained in |gui-mouse|. For scrolling
+with a mouse wheel see |scroll-mouse-wheel|.
+
+Don't forget to enable the mouse with this command: >
+ :set mouse=a
+Otherwise Vim won't recognize the mouse in all modes (See 'mouse').
+
+Currently the mouse is supported for Unix in an xterm window, in a *BSD
+console with |sysmouse|, in a Linux console (with GPM |gpm-mouse|), and
+in a Windows console.
+Mouse clicks can be used to position the cursor, select an area and paste.
+
+These characters in the 'mouse' option tell in which situations the mouse will
+be used by Vim:
+ n Normal mode
+ v Visual mode
+ i Insert mode
+ c Command-line mode
+ h all previous modes when in a help file
+ a all previous modes
+ r for |hit-enter| prompt
+
+The default for 'mouse' is empty, the mouse is not used. Normally you would
+do: >
+ :set mouse=a
+to start using the mouse (this is equivalent to setting 'mouse' to "nvich").
+If you only want to use the mouse in a few modes or also want to use it for
+the two questions you will have to concatenate the letters for those modes.
+For example: >
+ :set mouse=nv
+Will make the mouse work in Normal mode and Visual mode. >
+ :set mouse=h
+Will make the mouse work in help files only (so you can use "g<LeftMouse>" to
+jump to tags).
+
+Whether the selection that is started with the mouse is in Visual mode or
+Select mode depends on whether "mouse" is included in the 'selectmode'
+option.
+ *terminal-mouse*
+In an xterm, with the currently active mode included in the 'mouse' option,
+normal mouse clicks are used by Vim, mouse clicks with the shift or ctrl key
+pressed go to the xterm. With the currently active mode not included in
+'mouse' all mouse clicks go to the xterm.
+
+For terminals where it is not possible to have the mouse events be used by the
+terminal itself by using a modifier, a workaround is to not use mouse events
+for Vim in command-line mode: >
+ :set mouse=nvi
+Then to select text with the terminal, use ":" to go to command-line mode,
+select and copy the text to the system, then press Esc.
+
+Another way is to temporarily use ":sh" to run a shell, copy the text, then
+exit the shell. 'mouse' can remain set to "a" then.
+ *xterm-clipboard*
+In the Motif GUI version, when running in a terminal and there is
+access to the X-server (DISPLAY is set), the copy and paste will behave like
+in the GUI. If not, the middle mouse button will insert the unnamed register.
+In that case, here is how you copy and paste a piece of text:
+
+Copy/paste with the mouse and Visual mode ('mouse' option must be set, see
+above):
+1. Press left mouse button on first letter of text, move mouse pointer to last
+ letter of the text and release the button. This will start Visual mode and
+ highlight the selected area.
+2. Press "y" to yank the Visual text in the unnamed register.
+3. Click the left mouse button at the insert position.
+4. Click the middle mouse button.
+
+Shortcut: If the insert position is on the screen at the same time as the
+Visual text, you can do 2, 3 and 4 all in one: Click the middle mouse button
+at the insert position.
+
+Note: When the |-X| command line argument is used, Vim will not connect to the
+X server and copy/paste to the X clipboard (selection) will not work. Use the
+shift key with the mouse buttons to let the xterm do the selection.
+
+ *xterm-command-server*
+When the X-server clipboard is available, the command server described in
+|x11-clientserver| can be enabled with the --servername command line argument.
+
+ *xterm-copy-paste*
+NOTE: In some (older) xterms, it's not possible to move the cursor past column
+95 or 223. This is an xterm problem, not Vim's. Get a newer xterm
+|color-xterm|. Also see |'ttymouse'|.
+
+Copy/paste in xterm with (current mode NOT included in 'mouse'):
+1. Press left mouse button on first letter of text, move mouse pointer to last
+ letter of the text and release the button.
+2. Use normal Vim commands to put the cursor at the insert position.
+3. Press "a" to start Insert mode.
+4. Click the middle mouse button.
+5. Press ESC to end Insert mode.
+(The same can be done with anything in 'mouse' if you keep the shift key
+pressed while using the mouse.)
+
+Note: if you lose the 8th bit when pasting (special characters are translated
+into other characters), you may have to do "stty cs8 -istrip -parenb" in your
+shell before starting Vim.
+
+Thus in an xterm the shift and ctrl keys cannot be used with the mouse. Mouse
+commands requiring the CTRL modifier can be simulated by typing the "g" key
+before using the mouse:
+ "g<LeftMouse>" is "<C-LeftMouse> (jump to tag under mouse click)
+ "g<RightMouse>" is "<C-RightMouse> ("CTRL-T")
+
+ *mouse-mode-table* *mouse-overview*
+A short overview of what the mouse buttons do, when 'mousemodel' is "extend":
+
+Normal Mode:
+event position selection change action ~
+ cursor window ~
+<LeftMouse> yes end yes
+<C-LeftMouse> yes end yes "CTRL-]" (2)
+<S-LeftMouse> yes no change yes "*" (2) *<S-LeftMouse>*
+<LeftDrag> yes start or extend (1) no *<LeftDrag>*
+<LeftRelease> yes start or extend (1) no
+<MiddleMouse> yes if not active no put
+<MiddleMouse> yes if active no yank and put
+<RightMouse> yes start or extend yes
+<A-RightMouse> yes start or extend blockw. yes *<A-RightMouse>*
+<S-RightMouse> yes no change yes "#" (2) *<S-RightMouse>*
+<C-RightMouse> no no change no "CTRL-T"
+<RightDrag> yes extend no *<RightDrag>*
+<RightRelease> yes extend no *<RightRelease>*
+
+Insert or Replace Mode:
+event position selection change action ~
+ cursor window ~
+<LeftMouse> yes (cannot be active) yes
+<C-LeftMouse> yes (cannot be active) yes "CTRL-O^]" (2)
+<S-LeftMouse> yes (cannot be active) yes "CTRL-O*" (2)
+<LeftDrag> yes start or extend (1) no like CTRL-O (1)
+<LeftRelease> yes start or extend (1) no like CTRL-O (1)
+<MiddleMouse> no (cannot be active) no put register
+<RightMouse> yes start or extend yes like CTRL-O
+<A-RightMouse> yes start or extend blockw. yes
+<S-RightMouse> yes (cannot be active) yes "CTRL-O#" (2)
+<C-RightMouse> no (cannot be active) no "CTRL-O CTRL-T"
+
+In a help window:
+event position selection change action ~
+ cursor window ~
+<2-LeftMouse> yes (cannot be active) no "^]" (jump to help tag)
+
+When 'mousemodel' is "popup", these are different:
+
+Normal Mode:
+event position selection change action ~
+ cursor window ~
+<S-LeftMouse> yes start or extend (1) no
+<A-LeftMouse> yes start or extend blockw. no *<A-LeftMouse>*
+<RightMouse> no popup menu no
+
+Insert or Replace Mode:
+event position selection change action ~
+ cursor window ~
+<S-LeftMouse> yes start or extend (1) no like CTRL-O (1)
+<A-LeftMouse> yes start or extend blockw. no
+<RightMouse> no popup menu no
+
+(1) only if mouse pointer moved since press
+(2) only if click is in same buffer
+
+Clicking the left mouse button causes the cursor to be positioned. If the
+click is in another window that window is made the active window. When
+editing the command-line the cursor can only be positioned on the
+command-line. When in Insert mode Vim remains in Insert mode. If 'scrolloff'
+is set, and the cursor is positioned within 'scrolloff' lines from the window
+border, the text is scrolled.
+
+A selection can be started by pressing the left mouse button on the first
+character, moving the mouse to the last character, then releasing the mouse
+button. You will not always see the selection until you release the button,
+only in some versions (GUI, Win32) will the dragging be shown immediately.
+Note that you can make the text scroll by moving the mouse at least one
+character in the first/last line in the window when 'scrolloff' is non-zero.
+
+In Normal, Visual and Select mode clicking the right mouse button causes the
+Visual area to be extended. When 'mousemodel' is "popup", the left button has
+to be used while keeping the shift key pressed. When clicking in a window
+which is editing another buffer, the Visual or Select mode is stopped.
+
+In Normal, Visual and Select mode clicking the right mouse button with the alt
+key pressed causes the Visual area to become blockwise. When 'mousemodel' is
+"popup" the left button has to be used with the alt key. Note that this won't
+work on systems where the window manager consumes the mouse events when the
+alt key is pressed (it may move the window).
+
+ *double-click*
+Double, triple and quadruple clicks are supported when the GUI is active, for
+Win32, and for an xterm (if the gettimeofday() function is available). For
+selecting text, extra clicks extend the selection:
+ click select ~
+ double word or % match *<2-LeftMouse>*
+ triple line *<3-LeftMouse>*
+ quadruple rectangular block *<4-LeftMouse>*
+Exception: In a Help window a double click jumps to help for the word that is
+clicked on.
+A double click on a word selects that word. 'iskeyword' is used to specify
+which characters are included in a word. A double click on a character
+that has a match selects until that match (like using "v%"). If the match is
+an #if/#else/#endif block, the selection becomes linewise.
+For MS-Windows and xterm the time for double clicking can be set with the
+'mousetime' option. For the other systems this time is defined outside of Vim.
+An example, for using a double click to jump to the tag under the cursor: >
+ :map <2-LeftMouse> :exe "tag " .. expand("<cword>")<CR>
+
+Dragging the mouse with a double click (button-down, button-up, button-down
+and then drag) will result in whole words to be selected. This continues
+until the button is released, at which point the selection is per character
+again.
+
+For scrolling with the mouse see |scroll-mouse-wheel|.
+
+ *gpm-mouse*
+The GPM mouse is only supported when the |+mouse_gpm| feature was enabled at
+compile time. The GPM mouse driver (Linux console) does not support quadruple
+clicks.
+
+In Insert mode, when a selection is started, Vim goes into Normal mode
+temporarily. When Visual or Select mode ends, it returns to Insert mode.
+This is like using CTRL-O in Insert mode. Select mode is used when the
+'selectmode' option contains "mouse".
+ *sysmouse*
+The sysmouse is only supported when the |+mouse_sysmouse| feature was enabled
+at compile time. The sysmouse driver (*BSD console) does not support keyboard
+modifiers.
+
+ *drag-status-line*
+When working with several windows, the size of the windows can be changed by
+dragging the status line with the mouse. Point the mouse at a status line,
+press the left button, move the mouse to the new position of the status line,
+release the button. Just clicking the mouse in a status line makes that window
+the current window, without moving the cursor. If by selecting a window it
+will change position or size, the dragging of the status line will look
+confusing, but it will work (just try it).
+
+ *<MiddleRelease>* *<MiddleDrag>*
+Mouse clicks can be mapped. The codes for mouse clicks are:
+ code mouse button normal action ~
+ <LeftMouse> left pressed set cursor position
+ <LeftDrag> left moved while pressed extend selection
+ <LeftRelease> left released set selection end
+ <MiddleMouse> middle pressed paste text at cursor position
+ <MiddleDrag> middle moved while pressed -
+ <MiddleRelease> middle released -
+ <RightMouse> right pressed extend selection
+ <RightDrag> right moved while pressed extend selection
+ <RightRelease> right released set selection end
+ <X1Mouse> X1 button pressed - *X1Mouse*
+ <X1Drag> X1 moved while pressed - *X1Drag*
+ <X1Release> X1 button release - *X1Release*
+ <X2Mouse> X2 button pressed - *X2Mouse*
+ <X2Drag> X2 moved while pressed - *X2Drag*
+ <X2Release> X2 button release - *X2Release*
+
+The X1 and X2 buttons refer to the extra buttons found on some mice. The
+'Microsoft Explorer' mouse has these buttons available to the right thumb.
+Currently X1 and X2 only work on Win32 and X11 environments.
+
+Examples: >
+ :noremap <MiddleMouse> <LeftMouse><MiddleMouse>
+Paste at the position of the middle mouse button click (otherwise the paste
+would be done at the cursor position). >
+
+ :noremap <LeftRelease> <LeftRelease>y
+Immediately yank the selection, when using Visual mode.
+
+Note the use of ":noremap" instead of "map" to avoid a recursive mapping.
+>
+ :map <X1Mouse> <C-O>
+ :map <X2Mouse> <C-I>
+Map the X1 and X2 buttons to go forwards and backwards in the jump list, see
+|CTRL-O| and |CTRL-I|.
+
+ *mouse-swap-buttons*
+To swap the meaning of the left and right mouse buttons: >
+ :noremap <LeftMouse> <RightMouse>
+ :noremap <LeftDrag> <RightDrag>
+ :noremap <LeftRelease> <RightRelease>
+ :noremap <RightMouse> <LeftMouse>
+ :noremap <RightDrag> <LeftDrag>
+ :noremap <RightRelease> <LeftRelease>
+ :noremap g<LeftMouse> <C-RightMouse>
+ :noremap g<RightMouse> <C-LeftMouse>
+ :noremap! <LeftMouse> <RightMouse>
+ :noremap! <LeftDrag> <RightDrag>
+ :noremap! <LeftRelease> <RightRelease>
+ :noremap! <RightMouse> <LeftMouse>
+ :noremap! <RightDrag> <LeftDrag>
+ :noremap! <RightRelease> <LeftRelease>
