2. Introduction
GNU Emacs is one of the most commonly used text editor.
EMACS was written in 1976 by Richard Stallman and
Guy L. Steele, Jr. as a set of Editor MACroS for the
TECO editor.
Emacs uses special keys (ESC/Alt and CTRL) to perform editor functions .
This editor can do everything.
Emacs copies the contents of a file into a temporary buffer and we edit that. The file on disk doesn't change until we save the buffer. Like files, Emacs buffers have names. The name of a buffer is usually the same as the name of the file that we are editing.
