+  You are reading about GNU Emacs, the GNU incarnation of the
+advanced, self-documenting, customizable, extensible editor Emacs.
 (The `G' in `GNU' is not silent.)
 
-  We say that Emacs is a @dfn{display} editor because normally the text
-being edited is visible on the screen and is updated automatically as you
-type your commands.  @xref{Screen,Display}.
-
-  We call it a @dfn{real-time} editor because the display is updated very
-frequently, usually after each character or pair of characters you
-type.  This minimizes the amount of information you must keep in your
-head as you edit.  @xref{Basic,Real-time,Basic Editing}.
-
-  We call Emacs advanced because it provides facilities that go beyond
-simple insertion and deletion: controlling subprocesses; automatic
-indentation of programs; viewing two or more files at once; editing
-formatted text; and dealing in terms of characters, words, lines,
-sentences, paragraphs, and pages, as well as expressions and comments in
-several different programming languages.
+  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 change the definitions of Emacs
-commands in little 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, if you prefer the four basic cursor motion
-commands (up, down, left and right) on keys in a diamond pattern on the
-keyboard, you can rebind the keys that way.  @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 could have been written
-in Lisp but are written in C for efficiency.  Although only a programmer
-can write an extension, anybody can use it afterward.  @xref{Top,

    When running on a graphical display, Emacs provides its own menus

-the benefits of a graphical display even on a text-only terminal.  For
