There are several &cmdmode commands that add text to buffers; they
are
.*
:DL break.
.*
:DT.&lt."?&gt.&lt.n&gt.d&lt.oper&gt.
:DD.Deletes text in various ways.

:DT.&lt.n&gt.DEL
:DD.Deletes the character at the current cursor position.

:DT.D
:DD.Deletes text from the current cursor position to the end of the current line.

:DT.&lt.n&gt.x
:DD.Deletes the character at the current cursor position.

:DT.&lt.n&gt.X
:DD.Deletes the character before the current cursor position.

:DT.&lt."?&gt.&lt.n&gt.y&lt.oper&gt.
:DD.Yanks (copies) text in various ways.

:DT.&lt.n&gt.Y
:DD.Yanks (copies) the current line.
.*
:eDL.
.*
There is more information on these &cmdmode
commands later in this chapter.
.np
Text may be yanked/deleted into a specific &copybuffer
by typing "[1-9] before
the appropriate command. As well, there are 26 named buffers that may
be used, 'a'-'z'.  When text is yanked or deleted into a named buffer,
it remains there for the life of the editing session (or until replaced).
.np
To retrieve the contents of a buffer, use:
.*
.keylist begin 'Copy Buffers'
.*
.begkey SHIFT_INS &lt."?&gt.SHIFT_INS
Puts (pastes) the contents of the active &copybuffer
after the cursor position in the current edit buffer. 
.seecmd put
.np
.xmplsect begin
.begxmpl "aSHIFT_INS
Copy the data in the named buffer
.param a
after the current position in the file.
.endxmpl
.begxmpl SHIFT_INS
Copy the data in the active buffer
after the current position in the file.
.endxmpl
.xmplsect end
.endkey

.begkey p &lt."?&gt.p
Puts (pastes) the contents of the active &copybuffer
after the cursor position in the current edit buffer.
.seecmd put
.np
.xmplsect begin
.begxmpl p
Copies the data in the active buffer after the current position in the file.
.endxmpl
.begxmpl "5p
Copies the data in the numbered buffer
.param 5
after the current position in the file.
.endxmpl
.xmplsect end
.endkey

.begkey P &lt."?&gt.P
Puts (pastes) the contents of the active &copybuffer
before the cursor position in the current edit buffer.
.seecmd put
.np
.xmplsect begin
.begxmpl "aP
Copy the data in the named buffer
.param a
before the current position in the file.
.endxmpl
.begxmpl P
Copy the data in the active buffer
before the current position in the file.
.endxmpl
.xmplsect end
.endkey
.*
.keylist end
.*
.np
Without a
.param "?
prefix, these commands retrieve the contents of the active buffer.
.np
The contents of a &copybuffer
may be executed, as if the contents were typed from the
keyboard. See the
.keyword @
&cmdmode command later in this chapter.
.* ******************************************************************
.section *refid=srching 'Searching'
.* ******************************************************************
.np
The following &cmdmode commands are used for searching for text:
.*
.keylist begin Searching
.*
.begkey '/' '/' (forward slash)
Enter a regular expression to search for from current position forwards.
.endkey

.begkey ? ? (question mark)
Enter a regular expression to search for from current position backwards.
.endkey

.begkey n n
Repeat last search command, in the direction of the last search.
.endkey

.begkey N N
Repeat last search command, in the opposite direction of the last search.
.endkey
.*
.keylist end
.*
.np
For more information on regular expressions, see
:HDREF refid='rxchap'.
:period.
.np
Once you press the
.keyword /
or the
.keyword ?
keys, a search string entry window will appear:
.figure *depth='2.47' *scale='59' *file='vi022' Search String Entry Window
This position and size of the search string entry window are controlled
using
the
.keyref commandwindow
windowing command.
Search strings may be up to 512 bytes in length; the search string window
scrolls.
.np
The search string window has a history associated with it; the size
of this search string history is controlled using the
.keyref maxfindhistory
setting.  As well, the search string history is preserved across sessions of
&edvi if the
.keyref historyfile
parameter is set.
.np
If the first letter of a search string is a CTRL_A (entered by typing
a CTRL_V followed by a CTRL_A)
then that search string will not be added to the search string history.

:INCLUDE file='speckeys'.

.np
The following commands cause &edvi to go from &cmdmode
directly into &tinsmode:
.*
.keylist begin 'Inserting Text'
.*
.begkey INS INS

.endkey

.begkey a a
Starts appending (inserting) text after the current character in

.*
Once you are in &tinsmode, you can toggle back and forth between
