each selected line.
			See |visual-repeat|, |default-mappings|.

							*Q*
Q			Repeat the last recorded register [count] times.
			See |reg_recorded()|.

							*v_Q-default*
{Visual}Q		In linewise Visual mode, repeat the last recorded
			register for each selected line.
			See |visual-repeat|, |default-mappings|.

							*:@*
:[addr]@{0-9a-z".=*+}	Execute the contents of register {0-9a-z".=*+} as an Ex
			command.  First set cursor at line [addr] (default is
			current line).  When the last line in the register does
			not have a <CR> it will be added automatically when
			the 'e' flag is present in 'cpoptions'.
			For ":@=" the last used expression is used.  The
			result of evaluating the expression is executed as an
			Ex command.
			Mappings are not recognized in these commands.
			When the |line-continuation| character (\) is present
			at the beginning of a line in a linewise register,
			then it is combined with the previous line. This is
			useful for yanking and executing parts of a Vim
			script.

							*:@:*
:[addr]@:		Repeat last command-line.  First set cursor at line
			[addr] (default is current line).

:[addr]@							*:@@*
:[addr]@@		Repeat the previous :@{register}.  First set cursor at
			line [addr] (default is current line).

Using Vim scripts					*using-scripts*

For writing a Vim script, see chapter 41 of the user manual |usr_41.txt|.

					*:so* *:source* *load-vim-script*
:so[urce] {file}	Runs |Ex-commands| or Lua code (".lua" files) from
			{file}.
			Triggers the |SourcePre| autocommand.

:[range]so[urce]	Read Ex commands or Lua code from the [range] of lines
			in the current buffer.  When [range] is omitted read
			all lines.  The buffer is treated as Lua code if its
			'filetype' is "lua" or its filename ends with ".lua".

			When sourcing commands or Lua code from the current
			buffer, the same script-ID |<SID>| is used even if the
			buffer is sourced multiple times. If a buffer is
			sourced more than once, then the functions in the
			buffer are defined again.

							*:source!*
:so[urce]! {file}
			Runs |Normal-mode| commands from {file}. When used
			after |:global|, |:argdo|, |:windo|, |:bufdo|, in
			a loop or when another command follows the display
			won't be updated while executing the commands.

							*:ru* *:runtime*
:ru[ntime][!] [where] {file} ..
			Sources |Ex| commands or Lua code (".lua" files) read
			from {file} (a relative path) in each directory given
			by 'runtimepath' and/or 'packpath'.
			Ignores non-existing files.

			Example: >
				:runtime syntax/c.vim
				:runtime syntax/c.lua

<			There can be multiple space-separated {file}
			arguments. Each {file} is searched for in the first
			directory from 'runtimepath', then in the second
			directory, etc.

			When [!] is included, all found files are sourced.
			Else only the first found file is sourced.

			When [where] is omitted only 'runtimepath' is used.
			Other values:
				START	search only under "start" in 'packpath'
				OPT	search only under "opt" in 'packpath'
				PACK	search under "start" and "opt" in
					'packpath'
				ALL	first use 'runtimepath', then search
					under "start" and "opt" in 'packpath'

			When {file} contains wildcards it is expanded to all
			matching files.  Example: >
				:runtime! plugin/**/*.{vim,lua}
<			This is what Nvim uses to load the plugin files when
			starting up.  This similar command: >
				:runtime plugin/**/*.{vim,lua}
<			would source the first file only.

			For each {file} pattern, if two `.vim` and `.lua` file
			names match and differ only in extension, the `.vim`
			file is sourced first.

			When 'verbose' is one or higher, there is a message
			when no file could be found.
			When 'verbose' is two or higher, there is a message
			about each searched file.

							*:pa* *:packadd* *E919*
:pa[ckadd][!] {name}	Search for an optional plugin directory in 'packpath'
			and source any plugin
