Emacs Text Editor: Quick Reference

This FAQ will help refresh the memory of a user who has already had some experience with emacs.

Emacs is set up to insert text or accept commands at all times. Emacs uses <ctrl>, <alt>, and <esc> keys to distinguish text from commands. By default, it also comes up in its own window. The fonts and colors of this window can be changed with command line options or with defaults set in a $HOME/.Xdefaults file. For more information on emacs consult the man pages with man emacs or by using <ctrl> h or <esc> ? within emacs itself.

To invoke emacs type:

emacs filename &
