The following commands are used to shift lines to the right or left,
inserting or deleting leading whitespace. 
.se plural = 1
:INCLUDE file='oper'.
.*
.keylist begin 'Shifting Text'

.begkey &gt. &lt.n&gt.&gt.&lt.oper&gt. (right angle bracket)
This is the shift right command. It shifts the specified lines to the right
.keyref shiftwidth
spaces, inserting necessary leading tabs if
.keyref realtabs 1
is specified.
.np
A repeat count
.param &lt.n&gt.

units of the
.param &lt.oper&gt.
command to be shifted to the right.
.np

may be specified as
.param &gt.

which causes a single line to be shifted to the right.
.seecmd &gt.

.section 'Case Toggling'
.* ******************************************************************
.np
The case toggle &cmdmode command switches upper case letters to
lower case, and lower case letters to upper case.
 An example of its behaviour is changing the
line
.millust begin
This Is A Line Of Text.
.millust end
to
.millust begin
tHIS iS a lINE oF tEXT.
.millust end
.np
.se plural = 0
:INCLUDE file='oper'.
.*
.keylist begin 'Case Toggling'
.*
.begkey &tilde. &lt.n&gt.&tilde.&lt.oper&gt.  (tilde)
This is the case toggle command.
This command only works if the
.keyword togglecaselikevi
setting is not turned on.  If
.keyword togglecaselikevi
is set, then pressing
.param &tilde.
only changes the case of the current character, and advances the
cursor to the next character.
.np
However, if
.keyword togglecaselikevi
is not set, then this command toggles the case of the characters
over the range specified by
.param &lt.oper&gt.
.np
A repeat count
.param &lt.n&gt.
may precede the command, this causes
.param &lt.n&gt.
units of the
.param &lt.oper&gt.
command to be case toggled.
.np
.param &lt.oper&gt.
may be specified as
.param &tilde.
:cont.,
which causes a single line to be have its case toggled.
.np
.xmplsect begin
.begxmpl &tilde.r
Toggles the case of the currently selected (highlighted) range.
.endxmpl
.begxmpl &tilde.$
Toggles the case of all characters from the current column of the
current line to the last character of the current line.
.endxmpl
.begxmpl &tilde.w
Toggles the case of the current word.
.endxmpl
.begxmpl 10&tilde.&tilde.
Toggles the case of the current line and the 9 lines following.

.section 'Filters'
.* ******************************************************************
.np
The &cmdmode filter command has the same functionality as the
&cmdline command
.keyword filter
:period.
.se plural = 0
:INCLUDE file='oper'.
.*
.keylist begin Filters
.*
.begkey ! &lt.n&gt.!&lt.oper&gt. (exclamation mark)
Filter text. The line range specified by
.param &lt.oper&gt.
are run through a specified filter.
A repeat count
.param &lt.n&gt.
may precede the command, this causes
.param &lt.n&gt.
units of the
.param &lt.oper&gt.
command to be run through the filter.
.np
.param &lt.oper&gt.
may be specified as
.param !
:cont.,
which causes a single line to be run through the filter.
.np
The lines specified are run through a specified
system command (filter).  Once the filter range has been specified, a window
is displayed, prompting for a system command:
.figure *depth='2.47' *scale='59' *file='vi025' Filter System Command Prompt
The system command must take input from standard in and put
its output to standard out. The lines specified are replaced with the output
of the the command.
.np
There is a filter command history in the filter command prompt, the
size of which is controlled with the
.keyref maxfilterhistory
setting.
.seecmd !
.np
.xmplsect begin
.begxmpl !r
Runs the current selected (highlighted) region in the edit buffer
through a specified filter.
.endxmpl
.begxmpl !!
Runs the current line through a specified filter
.endxmpl
.begxmpl !G
Runs all lines from the current line to the end of the edit buffer
through a specified filter.

.section 'Text Selection'
.* ******************************************************************
.np
Text may be selected with the mouse. However, if you do not wish
to use the mouse, there is a keyboard interface to allow you to
accomplish the same thing.
.np

the selected region.   The selected region may be cleared, and
text selection ended, by
pressing the
.param ESC
key.

A selected region is highlighted by exchanging the foreground and
background the colors of the line.  A selected region could look
as follows:

The following are the &cmdmode commands for selecting text and
manipulating selected text.
.*
.keylist begin 'Text Selection'
