On first reading, just skim chapters 1 and 2, which describe the
notational conventions of the manual and the general appearance of the
Emacs display screen. Note which questions are answered in these
chapters, so you can refer back later. After reading chapter 4, you

@unnumbered Introduction
- You are reading about GNU Emacs, the GNU incarnation of the advanced,
-self-documenting, customizable, extensible real-time display editor Emacs.
+ 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,
-Emacs Lisp Intro, Preface, eintr, An Introduction to Programming in
-Emacs Lisp}, if you want to learn Emacs Lisp programming.
-
- When run under the X Window System, Emacs provides its own menus and
-convenient bindings to mouse buttons. But Emacs can provide many of the
-benefits of a window system on a text-only terminal. For instance, you
-can look at or edit several files at once, move text between files, and
-edit files while running shell commands.
+ @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}.
+
+ @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 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.
