The GNU Emacs Manual documents the use and simple customization of the popular Emacs editor. GNU Emacs is a member of the Emacs editor family. There are many Emacs editors, all sharing common principles of organization. This is primarily a reference manual, but can also be used as a primer. For complete beginners, it is a good idea to start with the on-line, learn-by-doing tutorial, before reading this manual. This way you can learn Emacs by using Emacs on a specially designed file which describes commands, tells you when to try them, and then explains the results you see. iUniverse.com Computer Books are composed of freely available online computer manuals, industry standard specifications, and electronically distributed computer-programming guides.
