			^      2 scr back    1 scr back     1 scr back

			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
			"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|.
			For the filter command, see |:range!|.

			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

			Vim builds command line using options 'shell', 'shcf',
			'sxq' and
