Various commands *various*
|
|
|
|
Type |gO| to see the table of contents.
|
|
|
|
==============================================================================
|
|
1. Various commands *various-cmds*
|
|
|
|
*CTRL-L*
|
|
CTRL-L Clears and redraws the screen. The redraw may happen
|
|
later, after processing typeahead.
|
|
See also |nvim__redraw()|.
|
|
*CTRL-L-default*
|
|
By default, also clears search highlighting
|
|
|:nohlsearch| and updates diffs |:diffupdate|.
|
|
|default-mappings|
|
|
|
|
*:mod* *:mode*
|
|
:mod[e] Clears and redraws the screen.
|
|
See also |nvim__redraw()|.
|
|
|
|
*:redr* *:redraw*
|
|
:redr[aw][!] Redraws pending screen updates now, or the entire
|
|
screen if "!" is included. To CLEAR the screen use
|
|
|:mode| or |CTRL-L|.
|
|
Useful to update the screen during a script or
|
|
function (or a mapping if 'lazyredraw' set).
|
|
See also |nvim__redraw()|.
|
|
|
|
*:redraws* *:redrawstatus*
|
|
:redraws[tatus][!] Redraws the status line and window bar of the current
|
|
window, or all status lines and window bars if "!" is
|
|
included. Redraws the commandline instead if it contains
|
|
the 'ruler'. Useful if 'statusline' or 'winbar' includes
|
|
an item that doesn't cause automatic updating.
|
|
See also |nvim__redraw()|.
|
|
|
|
*:redrawt* *:redrawtabline*
|
|
:redrawt[abline] Redraw the tabline. Useful to update the tabline when
|
|
'tabline' includes an item that doesn't trigger
|
|
automatic updating. See also |nvim__redraw()|.
|
|
|
|
*N<Del>*
|
|
<Del> When entering a number: Remove the last digit.
|
|
Note: if you like to use <BS> for this, add this
|
|
mapping to your vimrc: >
|
|
:map CTRL-V <BS> CTRL-V <Del>
|
|
<
|
|
:as[cii] or *ga* *:as* *:ascii*
|
|
ga Print the ascii value of the character under the
|
|
cursor in decimal, hexadecimal and octal.
|
|
Mnemonic: Get Ascii value.
|
|
|
|
For example, when the cursor is on a 'R':
|
|
<R> 82, Hex 52, Octal 122 ~
|
|
When the character is a non-standard ASCII character,
|
|
but printable according to the 'isprint' option, the
|
|
non-printable version is also given.
|
|
|
|
When the character is larger than 127, the <M-x> form
|
|
is also printed. For example:
|
|
<~A> <M-^A> 129, Hex 81, Octal 201 ~
|
|
<p> <|~> <M-~> 254, Hex fe, Octal 376 ~
|
|
(where <p> is a special character)
|
|
|
|
The <Nul> character in a file is stored internally as
|
|
<NL>, but it will be shown as:
|
|
<^@> 0, Hex 00, Octal 000 ~
|
|
|
|
If the character has composing characters these are
|
|
also shown. The value of 'maxcombine' doesn't matter.
|
|
|
|
If the character can be inserted as a digraph, also
|
|
output the two characters that can be used to create
|
|
the character:
|
|
<ö> 246, Hex 00f6, Oct 366, Digr o: ~
|
|
This shows you can type CTRL-K o : to insert ö.
|
|
|
|
|
|
*g8*
|
|
g8 Print the hex values of the bytes used in the
|
|
character under the cursor, assuming it is in |UTF-8|
|
|
encoding. This also shows composing characters. The
|
|
value of 'maxcombine' doesn't matter.
|
|
Example of a character with two composing characters:
|
|
e0 b8 81 + e0 b8 b9 + e0 b9 89 ~
|
|
|
|
*8g8*
|
|
8g8 Find an illegal UTF-8 byte sequence at or after the
|
|
cursor.
|
|
Can be used when editing a file that was supposed to
|
|
be UTF-8 but was read as if it is an 8-bit encoding
|
|
because it contains illegal bytes.
|
|
Does not wrap around the end of the file.
|
|
Note that when the cursor is on an illegal byte or the
|
|
cursor is halfway through a multibyte character the
|
|
command won't move the cursor.
|
|
|
|
*gx*
|
|
gx Opens the current filepath or URL (decided by
|
|
|<cfile>|, 'isfname') at cursor using the system
|
|
default handler, by calling |vim.ui.open()|.
|
|
|
|
*v_gx*
|
|
{Visual}gx Opens the selected text using the system default
|
|
handler, by calling |vim.ui.open()|.
|
|
|
|
*:p* *:pr* *:print* *E749*
|
|
:[range]p[rint] [flags]
|
|
Print [range] lines (default current line).
|
|
In the GUI you can use the File.Print menu entry.
|
|
See |ex-flags| for [flags].
|
|
The |:filter| command can be used to only show lines
|
|
matching a pattern.
|
|
|
|
:[range]p[rint] {count} [flags]
|
|
Print {count} lines, starting with [range] (default
|
|
current line |cmdline-ranges|).
|
|
See |ex-flags| for [flags].
|
|
|
|
*:l* *:list*
|
|
:[range]l[ist] [count] [flags]
|
|
Same as :print, but show tabs as ">", trailing spaces
|
|
as "-", and non-breakable space characters as "+" by
|
|
default. Further changed by the 'listchars' option.
|
|
See |ex-flags| for [flags].
|
|
|
|
*:nu* *:number*
|
|
:[range]nu[mber] [count] [flags]
|
|
Same as :print, but precede each line with its line
|
|
number. (See also |hl-LineNr| and 'numberwidth').
|
|
See |ex-flags| for [flags].
|
|
|
|
*:#*
|
|
:[range]# [count] [flags]
|
|
synonym for :number.
|
|
|
|
*:#!*
|
|
:#!{anything} Ignored, so that you can start a Vim script with: >
|
|
#!vim -S
|
|
echo "this is a Vim script"
|
|
quit
|
|
<
|
|
*:z* *E144*
|
|
:[range]z[+-^.=][count] Display several lines of text surrounding the line
|
|
specified with [range], or around the current line
|
|
if there is no [range].
|
|
|
|
If there is a [count], that's how many lines you'll
|
|
see; if there is no [count] and only one window then
|
|
twice the value of the 'scroll' option is used,
|
|
otherwise the current window height minus 3 is used.
|
|
This is the value of "scr" in the table below.
|
|
|
|
If there is a [count] the 'window' option is set to
|
|
its value.
|
|
|
|
:z can be used either alone or followed by any of
|
|
several marks. These have the following effect:
|
|
|
|
mark first line last line new cursor line ~
|
|
---- ---------- --------- ------------
|
|
+ current line 1 scr forward 1 scr forward
|
|
- 1 scr back current line current line
|
|
^ 2 scr back 1 scr back 1 scr back
|
|
. 1/2 scr back 1/2 scr fwd 1/2 scr fwd
|
|
= 1/2 scr back 1/2 scr fwd current line
|
|
|
|
Specifying no mark at all is the same as "+".
|
|
If the mark is "=", a line of dashes is printed
|
|
around the current line.
|
|
|
|
*:z!*
|
|
:[range]z![+-^.=][count]
|
|
Like ":z", but when [count] is not specified, it
|
|
defaults to the Vim window height minus one.
|
|
|
|
:[range]z[!]#[+-^.=][count] *:z#*
|
|
Like ":z" or ":z!", but number the lines.
|
|
|
|
*:=*
|
|
:= [args] Without [args]: prints the last line number.
|
|
With [args]: equivalent to `:lua ={expr}`. see |:lua|
|
|
|
|
:{range}= Prints the last line number in {range}. For example,
|
|
this prints the current line number: >
|
|
:.=
|
|
|
|
:norm[al][!] {commands} *:norm* *:normal*
|
|
Execute Normal mode commands {commands}. This makes
|
|
it possible to execute Normal mode commands typed on
|
|
the command-line. {commands} are executed like they
|
|
are typed. For undo all commands are undone together.
|
|
Execution stops when an error is encountered.
|
|
|
|
If the [!] is given, mappings will not be used.
|
|
Without it, when this command is called from a
|
|
non-remappable mapping (|:noremap|), the argument can
|
|
be mapped anyway.
|
|
|
|
{commands} should be a complete command. If
|
|
{commands} does not finish a command, the last one
|
|
will be aborted as if <Esc> or <C-C> was typed.
|
|
This implies that an insert command must be completed
|
|
(to start Insert mode, see |:startinsert|). A ":"
|
|
command must be completed as well. And you can't use
|
|
"Q" or "gQ" to start Ex mode.
|
|
|
|
The display is not updated while ":normal" is busy.
|
|
|
|
{commands} cannot start with a space. Put a count of
|
|
1 (one) before it, "1 " is one space.
|
|
|
|
This command cannot be followed by another command,
|
|
since any '|' is considered part of the command.
|
|
|
|
This command can be used recursively, but the depth is
|
|
limited by 'maxmapdepth'.
|
|
|
|
An alternative is to use |:execute|, which uses an
|
|
expression as argument. This allows the use of
|
|
printable characters to represent special characters.
|
|
|
|
Example: >
|
|
:exe "normal \<c-w>\<c-w>"
|
|
<
|
|
|
|
:{range}norm[al][!] {commands} *:normal-range*
|
|
Execute Normal mode commands {commands} for each line
|
|
in the {range}. Before executing the {commands}, the
|
|
cursor is positioned in the first column of the range,
|
|
for each line. Otherwise it's the same as the
|
|
":normal" command without a range.
|
|
|
|
*:sh* *:shell* *E371* *E360*
|
|
:sh[ell] Removed. |vim-differences|
|
|
|
|
*:terminal* *:te*
|
|
:te[rminal][!] [{cmd}] Run {cmd} in a non-interactive 'shell' in a new
|
|
|terminal-emulator| buffer. Without {cmd}, start an
|
|
interactive 'shell'.
|
|
|
|
Type |i| to enter |Terminal-mode|, then keys are sent to
|
|
the job running in the terminal. Type <C-\><C-N> to
|
|
leave Terminal-mode. |CTRL-\_CTRL-N|. Type <C-\><C-O>
|
|
to execute a single normal mode command |t_CTRL-\_CTRL-O|
|
|
|
|
Fails if changes have been made to the current buffer,
|
|
unless 'hidden' is set.
|
|
|
|
If {cmd} is omitted, and the 'shell' job exits with no
|
|
error, the buffer is closed automatically
|
|
|default-autocmds|.
|
|
|
|
To enter |Terminal-mode| automatically: >
|
|
autocmd TermOpen * startinsert
|
|
<
|
|
*:!cmd* *:!*
|
|
:!{cmd} Execute {cmd} with 'shell'. See also |:terminal|.
|
|
|
|
The command runs in a non-interactive shell connected
|
|
to a pipe (not a terminal). Use |:terminal| to run an
|
|
interactive shell connected to a terminal.
|
|
|
|
Backgrounded ("&") commands must not write to stdout
|
|
or stderr, the streams are closed immediately. |E5677|
|
|
Use |jobstart()| instead. >
|
|
:call jobstart('foo', {'detach':1})
|
|
<
|
|
For powershell, chaining a stringed executable path
|
|
requires using the call operator (&). >
|
|
:!Write-Output "1`n2" | & "C:\Windows\System32\sort.exe" /r
|
|
<
|
|
*E34*
|
|
Any "!" in {cmd} is replaced with the previous
|
|
external command (see also 'cpoptions'), unless
|
|
escaped by a backslash. Example: ":!ls" followed by
|
|
":!echo ! \! \\!" executes "echo ls ! \!".
|
|
|
|
Any "|" in {cmd} is passed to the shell, you cannot
|
|
use it to append a Vim command. See |:bar|.
|
|
|
|
Any "%" in {cmd} is expanded to the current file name.
|
|
Any "#" in {cmd} is expanded to the alternate file name.
|
|
Special characters are not escaped, use quotes or
|
|
|shellescape()|: >
|
|
:!ls "%"
|
|
:exe "!ls " .. shellescape(expand("%"))
|
|
<
|
|
Newline character ends {cmd} unless a backslash
|
|
precedes the newline. What follows is interpreted as
|
|
another |:| command.
|
|
|
|
After the command has been executed, the timestamp and
|
|
size of the current file is checked |timestamp|.
|
|
|
|
If the command produces too much output some lines may
|
|
be skipped so the command can execute quickly. No
|
|
data is lost, this only affects the display. The last
|
|
few lines are always displayed (never skipped).
|
|
|
|
To avoid the hit-enter prompt use: >
|
|
:silent !{cmd}
|
|
<
|
|
*:!!*
|
|
:!! Repeat last ":!{cmd}".
|
|
|
|
*:ve* *:ver* *:version*
|
|
:ve[rsion] Print editor version and build information.
|
|
See also |feature-compile|.
|
|
|
|
*:redi* *:redir*
|
|
:redi[r][!] > {file} Redirect messages to file {file}. The messages which
|
|
are the output of commands are written to that file,
|
|
until redirection ends. The messages are also still
|
|
shown on the screen. When [!] is included, an
|
|
existing file is overwritten. When [!] is omitted,
|
|
and {file} exists, this command fails.
|
|
|
|
Only one ":redir" can be active at a time. Calls to
|
|
":redir" will close any active redirection before
|
|
starting redirection to the new target. For recursive
|
|
use check out |execute()|.
|
|
|
|
To stop the messages and commands from being echoed to
|
|
the screen, put the commands in a function and call it
|
|
with ":silent call Function()".
|
|
Alternatives are the 'verbosefile' option or
|
|
|execute()| function, these can be used in combination
|
|
with ":redir".
|
|
|
|
:redi[r] >> {file} Redirect messages to file {file}. Append if {file}
|
|
already exists.
|
|
|
|
:redi[r] @{a-zA-Z}
|
|
:redi[r] @{a-zA-Z}> Redirect messages to register {a-z}. Append to the
|
|
contents of the register if its name is given
|
|
uppercase {A-Z}. The ">" after the register name is
|
|
optional.
|
|
:redi[r] @{a-z}>> Append messages to register {a-z}.
|
|
|
|
:redi[r] @*>
|
|
:redi[r] @+> Redirect messages to the selection or clipboard. For
|
|
backward compatibility, the ">" after the register
|
|
name can be omitted. See |quotestar| and |quoteplus|.
|
|
:redi[r] @*>>
|
|
:redi[r] @+>> Append messages to the selection or clipboard.
|
|
|
|
:redi[r] @"> Redirect messages to the unnamed register. For
|
|
backward compatibility, the ">" after the register
|
|
name can be omitted.
|
|
:redi[r] @">> Append messages to the unnamed register.
|
|
|
|
:redi[r] => {var} Redirect messages to a variable. If the variable
|
|
doesn't exist, then it is created. If the variable
|
|
exists, then it is initialized to an empty string.
|
|
The variable will remain empty until redirection ends.
|
|
Only string variables can be used. After the
|
|
redirection starts, if the variable is removed or
|
|
locked or the variable type is changed, then further
|
|
command output messages will cause errors. When using
|
|
a local variable (l:var in a function or s:var in a
|
|
script) and another `:redir` causes the current one to
|
|
end, the scope might be different and the assignment
|
|
fails.
|
|
To get the output of one command the |execute()|
|
|
function can be used instead of redirection.
|
|
|
|
:redi[r] =>> {var} Append messages to an existing variable. Only string
|
|
variables can be used.
|
|
|
|
:redi[r] END End redirecting messages.
|
|
|
|
*:filt* *:filter*
|
|
:filt[er][!] {pattern} {command}
|
|
:filt[er][!] /{pattern}/ {command}
|
|
Restrict the output of {command} to lines matching
|
|
with {pattern}. For example, to list only xml files: >
|
|
:filter /\.xml$/ oldfiles
|
|
< If the [!] is given, restrict the output of {command}
|
|
to lines that do NOT match {pattern}.
|
|
|
|
{pattern} is a Vim search pattern. Instead of enclosing
|
|
it in / any non-ID character (see |'isident'|) can be
|
|
used, so long as it does not appear in {pattern}.
|
|
Without the enclosing character the pattern cannot
|
|
include the bar character. 'ignorecase' is not used.
|
|
|
|
The pattern is matched against the relevant part of
|
|
the output, not necessarily the whole line. Only some
|
|
commands support filtering, try it out to check if it
|
|
works. Some of the commands that support filtering:
|
|
|:#| - filter whole line
|
|
|:clist| - filter by file name or module name
|
|
|:command| - filter by command name
|
|
|:files| - filter by file name
|
|
|:highlight| - filter by highlight group
|
|
|:history| - filter by history commands
|
|
|:jumps| - filter by file name
|
|
|:let| - filter by variable name
|
|
|:list| - filter whole line
|
|
|:llist| - filter by file name or module name
|
|
|:marks| - filter by text in the current file,
|
|
or file name for other files
|
|
|:oldfiles| - filter by file name
|
|
|:registers| - filter by register contents
|
|
(does not work multi-line)
|
|
|:set| - filter by option name
|
|
|
|
Only normal messages are filtered, error messages are
|
|
not.
|
|
|
|
*:sil* *:silent* *:silent!*
|
|
:sil[ent][!] {command} Execute {command} silently. Normal messages will not
|
|
be given or added to the message history.
|
|
When [!] is added, error messages will also be
|
|
skipped, and commands and mappings will not be aborted
|
|
when an error is detected. |v:errmsg| is still set.
|
|
When [!] is not used, an error message will cause
|
|
further messages to be displayed normally.
|
|
Redirection, started with |:redir|, will continue as
|
|
usual, although there might be small differences.
|
|
This will allow redirecting the output of a command
|
|
without seeing it on the screen. Example: >
|
|
:redir >/tmp/foobar
|
|
:silent g/Aap/p
|
|
:redir END
|
|
< To execute a Normal mode command silently, use the
|
|
|:normal| command. For example, to search for a
|
|
string without messages: >
|
|
:silent exe "normal /path\<CR>"
|
|
< ":silent!" is useful to execute a command that may
|
|
fail, but the failure is to be ignored. Example: >
|
|
:let v:errmsg = ""
|
|
:silent! /^begin
|
|
:if v:errmsg != ""
|
|
: ... pattern was not found
|
|
< ":silent" also skips the hit-enter prompt.
|
|
Dialogs that prompt for user input (|confirm()|,
|
|
'swapfile', …) are never silent.
|
|
|
|
*:uns* *:unsilent*
|
|
:uns[ilent] {command} Execute {command} not silently. Only makes a
|
|
difference when |:silent| was used to get to this
|
|
command.
|
|
Use this for giving a message even when |:silent| was
|
|
used. In this example |:silent| is used to avoid the
|
|
message about reading the file and |:unsilent| to be
|
|
able to list the first line of each file. >
|
|
:silent argdo unsilent echo expand('%') .. ": " .. getline(1)
|
|
<
|
|
|
|
*:verb* *:verbose*
|
|
:[count]verb[ose] {command}
|
|
Execute {command} with 'verbose' set to [count]. If
|
|
[count] is omitted one is used. ":0verbose" can be
|
|
used to set 'verbose' to zero.
|
|
The additional use of ":silent" makes messages
|
|
generated but not displayed.
|
|
The combination of ":silent" and ":verbose" can be
|
|
used to generate messages and check them with
|
|
|v:statusmsg| and friends. For example: >
|
|
:let v:statusmsg = ""
|
|
:silent verbose runtime foobar.vim
|
|
:if v:statusmsg != ""
|
|
: " foobar.vim could not be found
|
|
:endif
|
|
< When concatenating another command, the ":verbose"
|
|
only applies to the first one: >
|
|
:4verbose set verbose | set verbose
|
|
< verbose=4 ~
|
|
verbose=0 ~
|
|
For logging verbose messages in a file use the
|
|
'verbosefile' option.
|
|
|
|
*:verbose-cmd*
|
|
When 'verbose' is non-zero, listing the value of a Vim option or a key map or
|
|
an abbreviation or a user-defined function or a command or a highlight group
|
|
or an autocommand will also display where it was last defined. If they were
|
|
defined in Lua they will only be located if 'verbose' is set. So Start
|
|
nvim with -V1 arg to see them. If it was defined manually then there
|
|
will be no "Last set" message. When it was defined while executing a function,
|
|
user command or autocommand, the script in which it was defined is reported.
|
|
|
|
*K*
|
|
[count]K Runs the program given by 'keywordprg' to lookup the
|
|
|word| (defined by 'iskeyword') under or right of the
|
|
cursor. Default is "man". Works like this: >
|
|
:tabnew | terminal {program} {keyword}
|
|
< Special cases:
|
|
- If 'keywordprg' begins with ":" it is invoked as
|
|
a Vim command with [count].
|
|
- If 'keywordprg' is empty, |:help| is used.
|
|
- When 'keywordprg' is equal to "man", a [count]
|
|
before "K" is inserted after the "man" command and
|
|
before the keyword. For example, using "2K" while
|
|
the cursor is on "mkdir", results in: >
|
|
!man 2 mkdir
|
|
< - When 'keywordprg' is equal to "man -s", a [count]
|
|
before "K" is inserted after the "-s". If there is
|
|
no count, the "-s" is removed.
|
|
*K-lsp-default*
|
|
- The Nvim |LSP| client sets K to show LSP "hover"
|
|
feature. |lsp-defaults|
|
|
|
|
*v_K*
|
|
{Visual}K Like "K", but use the visually highlighted text for
|
|
the keyword. Only works when the highlighted text is
|
|
not more than one line.
|
|
|
|
*gO*
|
|
gO Show a filetype-specific, navigable "outline" of the
|
|
current buffer. For example, in a |help| buffer this
|
|
shows the table of contents.
|
|
|
|
Currently works in |help| and |:Man| buffers.
|
|
|
|
[N]gs *gs* *:sl* *:sleep*
|
|
:[N]sl[eep] [N][m] Do nothing for [N] seconds, or [N] milliseconds if [m]
|
|
was given. "gs" always uses seconds.
|
|
Default is one second. >
|
|
:sleep "sleep for one second
|
|
:5sleep "sleep for five seconds
|
|
:sleep 100m "sleep for 100 milliseconds
|
|
10gs "sleep for ten seconds
|
|
< Can be interrupted with CTRL-C.
|
|
"gs" stands for "goto sleep".
|
|
While sleeping the cursor is positioned in the text,
|
|
if at a visible position.
|
|
Queued messages are processed during the sleep.
|
|
|
|
*:sl!* *:sleep!*
|
|
:[N]sl[eep]! [N][m] Same as above. Unlike Vim, it does not hide the
|
|
cursor. |vim-differences|

2. Using Vim like less or more *less*
|
|
|
|
If you use the less or more program to view a file, you don't get syntax
|
|
highlighting. Thus you would like to use Vim instead. You can do this by
|
|
using the shell script "$VIMRUNTIME/macros/less.sh".
|
|
|
|
This shell script uses the Vim script "$VIMRUNTIME/macros/less.vim". It sets
|
|
up mappings to simulate the commands that less supports. Otherwise, you can
|
|
still use the Vim commands.
|
|
|
|
This isn't perfect. For example, when viewing a short file Vim will still use
|
|
the whole screen. But it works well enough for most uses, and you get syntax
|
|
highlighting.
|
|
|
|
The "h" key will give you a short overview of the available commands.
|
|
|
|
If you want to set options differently when using less, define the
|
|
LessInitFunc in your vimrc, for example: >
|
|
|
|
func LessInitFunc()
|
|
set nocursorcolumn nocursorline
|
|
endfunc
|
|
<
|
|

3. Commenting *commenting*
|
|
|
|
Nvim supports commenting and uncommenting of lines based on 'commentstring'.
|
|
|
|
Acting on a single line behaves as follows:
|
|
- If the line matches 'commentstring', the comment markers are removed (e.g.
|
|
`/*foo*/` is transformed to `foo`).
|
|
- Otherwise the comment markers are added to the current line (e.g. `foo` is
|
|
transformed to `/*foo*/`). Blank lines are ignored.
|
|
|
|
Acting on multiple lines behaves as follows:
|
|
- If each affected non-blank line matches 'commentstring', then all comment
|
|
markers are removed.
|
|
- Otherwise all affected lines are converted to comments; blank lines are
|
|
transformed to empty comments (e.g. `/**/`). Comment markers are aligned to
|
|
the least indented line.
|
|
|
|
Matching 'commentstring' does not account for whitespace in comment markers.
|
|
Removing comment markers is first attempted exactly, with fallback to using
|
|
markers trimmed from whitespace.
|
|
|
|
If the filetype of the buffer is associated with a language for which a
|
|
|treesitter| parser is installed, then |vim.filetype.get_option()| is called
|
|
to look up the value of 'commentstring' corresponding to the cursor position.
|
|
(This can be different from the buffer's 'commentstring' in case of
|
|
|treesitter-language-injections|.)
|
|
|
|
*gc* *gc-default*
|
|
gc{motion} Comment or uncomment lines covered by {motion}.
|
|
|
|
*gcc* *gcc-default*
|
|
gcc Comment or uncomment [count] lines starting at cursor.
|
|
|
|
*v_gc* *v_gc-default*
|
|
{Visual}gc Comment or uncomment the selected line(s).
|
|
|
|
*o_gc* *o_gc-default*
|
|
gc Text object for the largest contiguous block of
|
|
non-blank commented lines around the cursor (e.g.
|
|
`gcgc` uncomments a comment block; `dgc` deletes it).
|
|
Works only in Operator-pending mode.
