Zsh Line Editor

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.þ þ þ þ

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 SINGLE_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.þ þ þ þ þ

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 either of the VISUAL or EDITOR environment variables contains 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.

beginning-of-line-hist: Move to the beginning of the line. If already at the beginning of the buffer, move to the previous history line. þ

down-history (unbound) (^N): Move to the next event in the history list. þ

end-of-buffer-or-history (ESC->): Move to the end of the buffer, or if already there, move to the last event in the history list. þ
end-of-line-hist: Move to the end of the line. If already at the end of the buffer, move to the next history line. þ

vi-fetch-history (unbound) (G): Fetch the history line specified by the numeric argument. þ þ þ
history-incremental-search-backward (^R ^Xr): 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: backward-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 direction 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.þ þ
history-incremental-search-forward (^Xs): Search forward incrementally for a specified string. The string may begin with ^ to anchor the search to the beginning of the line. The functions available in the mini-buffer are the same as for history-incremental-search-backward.þ þ þ þ
history-search-backward (ESC-P ESC-p) (K): Search backward in the history for a line beginning with the first word in the buffer. þ þ
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.þ þ þ þ
history-search-forward (ESC-N ESC-n) (J): Search forward in the history for a line beginning with the first word in the buffer. þ þ
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 functions available in the mini-buffer are the same as for vi-history-search-backward.þ þ
infer-next-history (^X^N): Search in the history for a line matching the current one and fetch the event following it. þ þ þ
insert-last-word (ESC-_ ESC-.): Insert the last word from the previous history event at the cursor position. þ þ
vi-repeat-search (unbound) (n): Repeat the last vi history search. þ þ
vi-rev-repeat-search (unbound) (N): Repeat the last vi history search, but in reverse. þ þ þ þ

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. þ
up-line-or-search: 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. þ þ
up-history (unbound) (^P): Move to the previous event in the history list. þ
history-beginning-search-forward: Search forward in the history for a line beginning with the current line up to the cursor. This leaves the cursor at its original position.
