output like for |:list|
	#	add line number
	p	output like for |:print|

The flags can be combined, thus "l#" uses both a line number and |:list| style
output.

6. Ex special characters				*cmdline-special*

Note: These are special characters in the executed command line.  If you want
to insert special things while typing you can use the CTRL-R command.  For
example, "%" stands for the current file name, while CTRL-R % inserts the
current file name right away.  See |c_CTRL-R|.

Note:  If you want to avoid the effects of special characters in a Vim script
you may want to use |fnameescape()|.  Also see |`=|.


In Ex commands, at places where a file name can be used, the following
characters have a special meaning.  These can also be used in the expression
function |expand()|.
	%	Is replaced with the current file name.		  *:_%* *c_%*
	#	Is replaced with the alternate file name.	  *:_#* *c_#*
		This is remembered for every window.
	#n	(where n is a number) is replaced with		  *:_#0* *:_#n*
		the file name of buffer n.  "#0" is the same as "#".     *c_#n*
	##	Is replaced with all names in the argument list	  *:_##* *c_##*
		concatenated, separated by spaces.  Each space in a name
		is preceded with a backslash.
	#<n	(where n is a number > 0) is replaced with old	  *:_#<* *c_#<*
		file name n.  See |:oldfiles| or |v:oldfiles| to get the
		number.							*E809*

Note that these, except "#<n", give the file name as it was typed.  If an
absolute path is needed (when using the file name from a different directory),
you need to add ":p".  See |filename-modifiers|.

The "#<n" item returns an absolute path, but it will start with "~/" for files
below your home directory.

Note that backslashes are inserted before spaces, so that the command will
correctly interpret the file name.  But this doesn't happen for shell
commands.  For those you probably have to use quotes (this fails for files
that contain a quote and wildcards): >
	:!ls "%"
	:r !spell "%"

To avoid the special meaning of '%' and '#' insert a backslash before it.
Detail: The special meaning is always escaped when there is a backslash before
it, no matter how many backslashes.
	you type:		result	~
	   #			alternate.file
	   \#			#
	   \\#			\#

							*E499* *E500*
Note: these are typed literally, they are not special keys!
							*:<cword>* *<cword>*
	<cword>    is replaced with the word under the cursor (like |star|)
							*:<cWORD>* *<cWORD>*
	<cWORD>    is replaced with the WORD under the cursor (see |WORD|)
							*:<cexpr>* *<cexpr>*
	<cexpr>    is replaced with the word under the cursor, including more
		   to form a C expression.  E.g., when the cursor is on "arg"
		   of "ptr->arg" then the result is "ptr->arg"; when the
		   cursor is on "]" of "list[idx]" then the result is
		   "list[idx]".
							*:<cfile>* *<cfile>*
	<cfile>    is replaced with the path name under the cursor (like what
		   |gf| uses)
							*:<afile>* *<afile>*
	<afile>    When executing autocommands, is replaced with the file name
		   of the buffer being manipulated, or the file for a read or
		   write.  *E495*
							*:<abuf>* *<abuf>*
	<abuf>     When executing autocommands, is replaced with the currently
		   effective buffer number.  It is not set for all events,
		   also see |bufnr()|.  For ":r file" and ":so file" it is the
		   current buffer, the file being read/sourced is not in a
		   buffer.  *E496*
							*:<amatch>* *<amatch>*
	<amatch>   When executing autocommands, is replaced with the match for
		   which this autocommand was executed.  *E497*
		   It differs from <afile> when the file name isn't used to
		   match with (for FileType, Syntax and SpellFileMissing
		   events).
		   When the match is with a file name, it is expanded to the
		   full path.
							*:<sfile>* *<sfile>*
	<sfile>    When executing a `:source` command, is replaced with the
		   file name of the sourced file.  *E498*
