advanced, self-documenting, customizable, extensible editor Emacs.
(The `G' in `GNU' is not silent.)
- We call Emacs advanced because it provides much more than simple
-insertion and deletion. It can control subprocesses, indent programs
-automatically, show two or more files at once, and edit formatted
-text. Emacs editing commands operate in terms of characters, words,
-lines, sentences, paragraphs, and pages, as well as expressions and
-comments in various programming languages.
-
- @dfn{Self-documenting} means that at any time you can type a special
-character, @kbd{Control-h}, to find out what your options are. You can
-also use it to find out what any command does, or to find all the commands
-that pertain to a topic. @xref{Help}.
-
- @dfn{Customizable} means that you can alter Emacs commands' behavior
-in simple ways. For example, if you use a programming language in
-which comments start with @samp{<**} and end with @samp{**>}, you can
-tell the Emacs comment manipulation commands to use those strings
-(@pxref{Comments}). Another sort of customization is rearrangement of
-the command set. For example, you can rebind the basic cursor motion
-commands (up, down, left and right) to any keys on the keyboard that
-you find comfortable. @xref{Customization}.

+can rebind the basic cursor motion commands (up, down, left and right)
+to any keys on the keyboard that you find comfortable.
+@xref{Customization}.
@dfn{Extensible} means that you can go beyond simple customization
-and write entirely new commands---programs in the Lisp language to be
-run by Emacs's own Lisp interpreter. Emacs is an ``on-line
-extensible'' system, which means that it is divided into many
-functions that call each other, any of which can be redefined in the
-middle of an editing session. Almost any part of Emacs can be
-replaced without making a separate copy of all of Emacs. Most of the
-editing commands of Emacs are written in Lisp; the few exceptions
+and create entirely new commands. New commands are simply programs
+written in the Lisp language, which are run by Emacs's own Lisp
+interpreter. Existing commands can even be redefined in the middle of
+an editing session, without having to restart Emacs. Most of the
+editing commands in Emacs are written in Lisp; the few exceptions
could have been written in Lisp but use C instead for efficiency.
Writing an extension is programming, but non-programmers can use it
afterwards. @xref{Top, Emacs Lisp Intro, Preface, eintr, An
Introduction to Programming in Emacs Lisp}, if you want to learn Emacs
Lisp programming.
- When running on a graphical display, Emacs provides its own menus
-and convenient handling of mouse buttons. In addition, Emacs provides
-many of the benefits of a graphical display even on a text-only
-terminal. For instance, it can highlight parts of a file, display and
-edit several files at once, move text between files, and edit files
-while running shell commands.
