8.4.8 Some Miscellaneous Commands

re-read-init-file (C-x C-r)

abort (C-g)

Abort the current editing command and ring the terminal's bell (subject to the setting of bell-style).

do-uppercase-version (M-a, M-b, M-x, ...)

If the metafied character x is lowercase, run the command that is bound to the corresponding uppercase character.

prefix-meta (ESC)

Metafy the next character typed. This is for keyboards without a meta key. Typing `ESC f' is equivalent to typing M-f.

undo (C-_ or C-x C-u)

Undo all changes made to this line. This is like executing the undo command enough times to get back to the beginning.

tilde-expand (M-&)

set-mark (C-@)

Set the mark to the point. If a numeric argument is supplied, the mark is set to that position.

Swap the point with the mark. The current cursor position is set to the saved position, and the old cursor position is saved as the mark.

character-search (C-])

A character is read and point is moved to the next occurrence of that character. A negative count searches for previous occurrences.

character-search-backward (M-C-])

A character is read and point is moved to the previous occurrence of that character. A negative count searches for subsequent occurrences.

insert-comment (M-#)

The value of the comment-begin variable is inserted at the beginning of the current line, and the line is accepted as if a newline had been typed. The default value of comment-begin causes this command to make the current line a shell comment.

dump-functions ()
