for shifting multiple 'shiftwidth's.

:[range]le[ft] [indent]	left align lines in [range].  Sets the indent in the
			lines to [indent] (default 0).

							*:>*
:[range]> [flags]	Shift [range] lines one 'shiftwidth' right.
			Repeat '>' for shifting multiple 'shiftwidth's.
			See |ex-flags| for [flags].

:[range]> {count} [flags]
			Shift {count} lines one 'shiftwidth' right, starting
			with [range] (default current line |cmdline-ranges|).
			Repeat '>' for shifting multiple 'shiftwidth's.
			See |ex-flags| for [flags].

The ">" and "<" commands are handy for changing the indentation within
programs.  Use the 'shiftwidth' option to set the size of the white space
which these commands insert or delete.  Normally the 'shiftwidth' option is 8,
but you can set it to, say, 3 to make smaller indents.  The shift leftwards
stops when there is no indent.  The shift right does not affect empty lines.

If the 'shiftround' option is on, the indent is rounded to a multiple of
'shiftwidth'.

If the 'smartindent' option is on, or 'cindent' is on and 'cinkeys' contains
'#' with a zero value, shift right does not affect lines starting with '#'
(these are supposed to be C preprocessor lines that must stay in column 1).
This can be changed with the 'cino' option, see |cino-#|.

When the 'expandtab' option is off (this is the default) Vim uses <Tab>s as
much as possible to make the indent.  You can use ">><<" to replace an indent
made out of spaces with the same indent made out of <Tab>s (and a few spaces
if necessary).  If the 'expandtab' option is on, Vim uses only spaces.  Then
you can use ">><<" to replace <Tab>s in the indent by spaces (or use
`:retab!`).

To move a line several 'shiftwidth's, use Visual mode or the `:` commands.
For example: >
	Vjj4>		move three lines 4 indents to the right
	:<<<		move current line 3 indents to the left
	:>> 5		move 5 lines 2 indents to the right
	:5>>		move line 5 2 indents to the right

4.1 Filter commands					*filter*

A filter is a program that accepts text at standard input, changes it in some
way, and sends it to standard output.  You can use the commands below to send
some text through a filter, so that it is replaced by the filter output.
Examples of filters are "sort", which sorts lines alphabetically, and
"indent", which formats C program files (you need a version of indent that
works like a filter; not all versions do).  The 'shell' option specifies the
shell Vim uses to execute the filter command.  You can repeat filter commands
with ".".  Vim does not recognize a comment (starting with '"') after the
`:!` command.

							*!*
!{motion}{filter}	Filter {motion} text lines through the external
			program {filter}.

							*!!*
!!{filter}		Filter [count] lines through the external program
			{filter}.

							*v_!*
{Visual}!{filter}	Filter the highlighted lines through the external
			program {filter} (for {Visual} see |Visual-mode|).

:{range}![!]{filter} [!][arg]				*:range!*
			For executing external commands see |:!|

			Filter {range} lines through the external program
			{filter}.  Vim replaces the optional bangs with the
			latest given command and appends the optional [arg].
			Vim saves the output of the filter command in a
			temporary file and then reads the file into the buffer
			|tempfile|.  Vim uses the 'shellredir' option to
			redirect the filter output to the temporary file.
			However, if the 'shelltemp' option is off then pipes
			are used when possible (on Unix).
			When the 'R' flag is included in 'cpoptions' marks in
			the filtered lines are deleted, unless the
			|:keepmarks| command is used.  Example: >
				:keepmarks '<,'>!sort
<			When the number of lines after filtering is less than
			before, marks in the missing lines are deleted anyway.

							*=*
={motion}		Filter {motion} lines through the external program
			given with the 'equalprg' option.
