The Emacs Command Set

This page will list most of the default command set that comes with GNU-Emacs.

Line breaks are represented as single Newline characters, regardless of the representation used by the operating system.

Notation

The Escape key (usually labelled "Esc") which sends the escape character is used as a prefix to make up for the missing Meta shift key. By convention, those keyboards that have an extra shift key (perhaps labelled Meta or Alt) can specify meta commands by setting bit 2^7 in characters sent from the keyboard.

Emacs commands are, by convention, always upper/lower case-independent. Thus, ^X B and ^X b both refer to the same command. The only exception is the "self-insert" command, where B inserts a "B" and b inserts a "b". Only the uppercase versions will be listed.
