Documentation

Major mode for examining and redoing commands from command-history(var)/command-history(fun).

This pops up a window with the Command History listing. The number of command listed is controlled by list-command-history-max. The command history is filtered by list-command-history-filter if non-nil. Combines typeout Command History list window with menu like selection of an expression from the history for re-evaluation in the *original* buffer.

The history displayed is filtered by list-command-history-filter if non-nil.

Like Emacs-Lisp mode except that characters do not insert themselves and Tab and Linefeed do not indent. Instead these commands are provided:
! Electric-command-history-redo-expression
<down> next-line
<home> beginning-of-buffer
<next> scroll-up
<prior> scroll-down
<t> Electric-history-undefined
<up> previous-line

ESC <t> Electric-history-undefined
M-< beginning-of-buffer
M-> end-of-buffer
M-v scroll-down
RET next-line
SPC Electric-command-history-redo-expression
q Electric-history-quit

Calls the value of electric-command-history-hook if that is non-nil. The Command History listing is recomputed each time this mode is invoked.

Probably introduced at or before Emacs version 16.
