Editing with GNU Emacs

This chapter describes the Unix version of GNU Emacs. In addition to GNU Emacs, a "smaller" version called MicroGNUEmacs (or "mg") is also available. Versions of Emacs also exist for various microcomputers. Of course, "mg" and the microcomputer versions don't have as many features as GNU Emacs, but they operate similarly.

Another editor is available called "vi". It has been available on Unix systems longer than Emacs, but GNU Emacs is gaining in popularity. You may want to use "vi" if your colleagues already use "vi". If you have a choice, however, learning GNU Emacs is recommended.
