z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

line is a ). When a line ends with white space, vi retains the white space,
does not add any further spaces, and then appends the next line.
p Same as p except that text is pasted before the cursor instead of after it.
P Put buffer contents before the cursor. Also called a paste operation. If
preceded by quote buffername (for example, “b), the contents of that buffer
are used; otherwise the contents of the unnamed buffer are used. If the
buffer was created in ex mode, the contents of the buffer are inserted
before the current line. If the buffer was created in vi mode, the contents
are inserted before the cursor. As a special case, if a paste operation is
repeated with the period (.) command and it used a numbered buffer, the
number of the buffer is incremented. Thus, “1p ..., pastes in the contents of
buffer 1 through buffer 6; in other words the last six things that were deleted
are put back.
Q Switches to ex mode. You leave vi mode and the ex prompt is shown on
the bottom line of the screen.
U Undoes all changes to current line. As soon as you move off a line or
invoke an ex command on the line, the original contents of the line are
forgotten and U is not successful.
u Undoes last change. If repeated, you undo the undo (that is, go back to
what the text was before the undo). Some operations are treated as single
changes; for example, everything done by a global G is undone with undo.
ZZ Writes the file out, if changed, and then exits.
. Repeats the last command. Any command that changes the contents of the
file can be repeated by this command. If you do not specify count with the .
command, vi uses the count that was specified for the command being
repeated.
~ Toggles the case of the character under the cursor and moves the cursor
right by one. This command can be preceded by count to change the case
of count characters.
& Repeats the previous ex substitute command, using the current line as the
target. Flags set by the previous command are ignored. Equivalent to the
ex command &.
: Invokes a single ex command. The editor places the cursor on the bottom
line of the screen and displays a colon (:) to prompt for input. You can then
type one or more ex commands; when you press ESC or a RETURN, the
line you have entered is passed to ex and executed there.
@ Invokes a macro. When the next character is a letter from a through z, vi
treats it as the name of a buffer. The contents of that buffer are treated as
input typed to vi. The text of a macro may contain an @ calling another
macro. A macro may call itself, provided it is invoked at the end of the
macro (tail recursion). Such a macro executes forever or until an error
occurs or the INTERRUPT key is pressed. A macro that invokes itself at the
beginning (head recursion) loops until it runs out of memory. A vi error
terminates all currently executing macros. All changes made during a macro
call are treated as a unit and may be undone with a single u command.
= Reindents the specified line as though they were set via lisp and
autoindent-set, if the lisp option was specified.
