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*
|
|
|
|
When Vim is started a default terminal type is assumed. for MS-DOS this is
|
|
the pc terminal, for Unix an ansi terminal.
|
|
|
|
*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|.
|
|
|
|
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' 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' and
|
|
't_ke' will be sent to the terminal.
|
|
|
|
*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.
|
|
|
|
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.
|
|
|
|
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.
|
|
*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.
|
|
|
|
==============================================================================
|
|
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' 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.

t_KL <k9> keypad 9 *<k9>* *t_KL* *'t_KL'*
|
|
<Mouse> leader of mouse code *<Mouse>*
|
|
|
|
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.
|
|
Note: This is only done on startup. If the xterm options are changed after
|
|
Vim has started, the escape sequences may not be recognized any more.
|
|
|
|
*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.
|
|
|
|
*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.
|
|
|
|
*termcap-cursor-shape* *termcap-cursor-color*
|
|
When Vim enters Insert mode the 't_SI' escape sequence is sent. When leaving
|
|
Insert mode 't_EI' is used. But only if both are defined. This can be used
|
|
to change the shape or color of the cursor in Insert 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_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.
|
|
{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, 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. A known exception is the MS-DOS console
|
|
(pcterm). 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. It defaults to "yes" when 'term' is
|
|
"pcterm".
|
|
|
|
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.]
|
|
|
|
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* *E362*
|
|
:mod[e]
|
|
|
|
Detects the screen size and redraws the screen.
|
|
|
|
==============================================================================
|
|
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 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 (does not work for MS-DOS). 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|.
|
|
|
|
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
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
*xterm-clipboard*
|
|
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.
|
|
|
|
*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|.
|
|
|
|
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")
|
|
|
|
*bracketed-paste-mode*
|
|
Bracketed paste mode allows terminal emulators to distinguish between typed
|
|
text and pasted text.
|
|
|
|
For terminal emulators that support it, this mode is enabled by default. Thus
|
|
you can paste text without Neovim giving any special meaning to it. Most
|
|
notably it won't try reindenting those lines.
|
|
|
|
If your terminal emulator doesn't support it yet, you can get the old Vim
|
|
behaviour by enabling |'paste'| temporarily.
|
|
|
|
NOTE: See https://cirw.in/blog/bracketed-paste for technical details.
|
|
|
|
*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, MS-DOS, 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 MS-DOS and 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-DOS 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.
|
|
|
|
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".
|
|
*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 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: >
|
