NAME
zshzle - zsh command line editor
DESCRIPTION
If the ZLE option is set (it is by default) and the shell
input is attached to the terminal, the user is allowed to
edit command lines.
There are two display modes. The first, multiline mode,
is the default. It only works if the TERM parameter is
set to a valid terminal type that can move the cursor up.
The second, single line mode, is used if TERM is invalid
or incapable of moving the cursor up, or if the SIN-
GLE_LINE_ZLE option is set. This mode is similar to ksh,
and uses no termcap sequences. If TERM is "emacs", the
ZLE option will be unset by the shell.
Bindings
Command bindings may be set using the bindkey builtin.
There are two keymaps-the main keymap and the alternate
keymap. The alternate keymap is bound to vi command mode.
The main keymap is bound to emacs mode by default. To
bind the main keymap to vi insert mode, use bindkey -v.
However, if one of the VISUAL or EDITOR environment vari-
ables contain the string vi when the shell starts up the
main keymap will be bound to vi insert mode by default.
The following is a list of all the key commands and their
default bindings in emacs and vi command mode.

Move down a line in the buffer, or if already at
the bottom line, move to the next event in the his-
tory list.
vi-down-line-or-history (unbound) (+)
Move down a line in the buffer, or if already at
the bottom line, move to the next event in the his-
tory list. Then move to the first non-blank
character on the line.
down-line-or-search
Move down a line in the buffer, or if already at
the bottom line, search forward in the history for
a line beginning with the first word in the buffer.
down-history (unbound) (^N)
Move to the next event in the history list.
history-beginning-search-backward
Search backward in the history for a line beginning
with the current line up to the cursor. This
leaves the cursor in its original position.

vi-fetch-history (unbound) (G)
Fetch the history line specified by the numeric
argument. This defaults to the current history
line (i.e. the one that isn't history yet).
history-incremental-search-backward (^R ^Xr) (unbound)
Search backward incrementally for a specified
string. The string may begin with `^' to anchor
the search to the beginning of the line. A
restricted set of editing functions is available in
the mini-buffer. An interrupt signal, as defined by
the stty setting, will stop the search and go back
to the original line. An undefined key will have
the same effect. The supported functions are: back-
ward-delete-char, quoted-insert, accept-and-hold,
accept-and-infer-next-history, accept-line and
accept-line-and-down-history; magic-space just
inserts a space. Any string that is bound to an
out-string (via bindkey -s) will behave as if out-
string were typed directly. Typing the binding of
history-incremental-search-backward will get the
next occurrence of the contents of the mini-buffer.
Typing the binding of history-incremental-search-
forward inverts the sense of the search. The direc-
tion of the search is indicated in the mini-buffer.
Any multi-character string that is not bound to one
of the above functions will beep and interrupt the
search, leaving the last found line in the buffer.
Any single character that is not bound to one of
the above functions, or self-insert or self-insert-
unmeta, will have the same effect but the function
will be executed.
history-incremental-search-forward (^Xs) (unbound)
Search forward incrementally for a specified
string. The string may begin with `^' to anchor
the search to the beginning of the line. The func-
tions available in the mini-buffer are the same as
for history-incremental-search-backward.
history-search-backward (ESC-P ESC-p) (unbound)
Search backward in the history for a line beginning
with the first word in the buffer.
vi-history-search-backward (unbound) (?)
Search backward in the history for a specified
string. The string may begin with `^' to anchor
the search to the beginning of the line. A
restricted set of editing functions is available in
the mini-buffer. An interrupt signal, as defined by
the stty setting, will stop the search, as will a
character bound to vi-cmd-mode. The functions
available in the mini-buffer are: accept-line,
backward-delete-char, vi-backward-delete-char and
quoted-insert. Any string that is bound to an out-
string (via bindkey -s) will behave as if out-
string were typed directly. Any other character
that is not bound to self-insert or self-insert-
unmeta will beep and be ignored. If the function is
called from vi command mode, the bindings of vi
insert mode will be used.
history-search-forward (ESC-N ESC-n) (unbound)
Search forward in the history for a line beginning
with the first word in the buffer.
vi-history-search-forward (unbound) (/)
Search forward in the history for a specified
string. The string may begin with `^' to anchor
the search to the beginning of the line. The func-
tions available in the mini-buffer are the same as
for vi-history-search-backward.
infer-next-history (^X^N) (unbound)
Search in the history list for a line matching the
current one and fetch the event following it.
insert-last-word (ESC-_ ESC-.) (unbound)

default is lexical history unless the HISTLIT
option is set.
up-line-or-history (^P ESC-[A) (k)
Move up a line in the buffer, or if already at the
top line, move to the previous event in the history
list.
vi-up-line-or-history (unbound) (-)
Move up a line in the buffer, or if already at the
top line, move to the previous event in the history
list. Then move to the first non-blank character
on the line.

Move up a line in the buffer, or if already at the
top line, search backward in the history for a line
beginning with the first word in the buffer.
up-history (unbound) (^P)
Move to the previous event in the history list.
history-beginning-search-forward
Search forward in the history for a line beginning
with the current line up to the cursor. This

stack.
accept-line (^J ^M) (^J ^M)
Execute the contents of the buffer.
accept-line-and-down-history (^O) (unbound)
Execute the current line, and push the next history
event on the the buffer stack.
vi-cmd-mode (^X^V) (^[)
Enter command mode; that is, use the alternate
keymap. Yes, this is bound by default in emacs
mode.
vi-caps-lock-panic

TIVE_COMMENTS option must be set for this to have
any usefulness.
vi-pound-insert (unbound) (#)
If there is no # character at the beginning of the
current line, add one. If there is one, remove it.
The INTERACTIVE_COMMENTS option must be set for
this to have any usefulness.
push-input
Push the entire current multiline construct onto
the buffer stack and return to the top-level (PS1)
prompt. If the current parser construct is only a
single line, this is exactly like push-line. Next
time the editor starts up or is popped with get-
line, the construct will be popped off the top of
the buffer stack and loaded into the editing
buffer.
push-line (^Q ESC-Q ESC-q) (unbound)
Push the current buffer onto the buffer stack and
clear the buffer. Next time the editor starts up,
the buffer will be popped off the top of the buffer
stack and loaded into the editing buffer.
push-line-or-edit
At the top-level (PS1) prompt, equivalent to push-
line. At a secondary (PS2) prompt, move the entire
current multiline construct into the editor buffer.
The latter is equivalent to push-input followed by
get-line.
redisplay (unbound) (^R)
Redisplays the edit buffer.
send-break (^G) (unbound)
Abort the current editor function, eg. execute-
named-command, or the editor itself, eg. if you are

Read the name of an editor command and and print
the listing of key sequences that invoke the speci-
fied command.
which-command (ESC-?) (unbound)
Push the buffer onto the buffer stack, and execute
the command "which-command cmd", where cmd is the
current command. which-command is normally aliased
to whence.
vi-digit-or-beginning-of-line (unbound) (0)
