@unnumbered Preface

  This manual documents the use and simple customization of the Emacs
editor.  Simple Emacs customizations do not require you to be a
programmer, but if you are not interested in customizing, you can
ignore the customization hints.

  This is primarily a reference manual, but can also be used as a
primer.  If you are new to Emacs, we recommend you start with the
integrated, learn-by-doing tutorial, before reading the manual.  To
run the tutorial, start Emacs and type @kbd{C-h t} (which is ``control
h and then t'').  The tutorial describes commands, tells you when to
try them, and explains the results.  The tutorial is available in
several languages.

  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
should practice the commands shown there.  The next few chapters
describe fundamental techniques and concepts that are used constantly.
You need to understand them thoroughly, so experiment with them
until you are fluent.

  Chapters 14 through 19 describe intermediate-level features that are
useful for many kinds of editing.  Chapter 20 and following chapters
describe optional but useful features; read those chapters when you
need them.

  Read the Common Problems chapter if Emacs does not seem to be
working properly.  It explains how to cope with several common
problems (@pxref{Lossage,, Dealing with Emacs Trouble}), as well as
when and how to report Emacs bugs (@pxref{Bugs}).

  To find the documentation of a particular command, look in the index.
Keys (character commands) and command names have separate indexes.
There is also a glossary, with a cross reference for each term.

  This manual is available as a printed book and also as an Info file.
The Info file is for reading from Emacs itself, or with the Info program.
Info is the principal format for documentation in the GNU system.
The Info file and the printed book contain substantially the same text
and are generated from the same source files, which are also
distributed with GNU Emacs.

  GNU Emacs is a member of the Emacs editor family.  There are many
Emacs editors, all sharing common principles of organization.  For
information on the underlying philosophy of Emacs and the lessons
learned from its development, see @cite{Emacs, the Extensible,
Customizable Self-Documenting Display Editor}, available from
@url{https://dspace.mit.edu/handle/1721.1/5736}.

This version of the manual is mainly intended for use with GNU Emacs
installed on GNU and Unix systems.  GNU Emacs can also be used on
MS-DOS, Microsoft Windows, and Macintosh systems.  The Info file
version of this manual contains some more information about using
Emacs on those systems.  Those systems use different file name syntax;
in addition MS-DOS does not support all GNU Emacs features.
@xref{Microsoft Windows}, for information about using Emacs on
Windows.  @xref{Mac OS / GNUstep}, for information about using Emacs
on Macintosh (and GNUstep).

@unnumbered Distribution

GNU Emacs is @dfn{free software}; this means that everyone is free to
use it and free to redistribute it under certain conditions.  GNU Emacs
is not in the public domain; it is copyrighted and there are
restrictions on its distribution, but these restrictions are designed
to permit everything that a good cooperating citizen would want to do.
What is not allowed is to try to prevent others from further sharing
any version of GNU Emacs that they might get from you.  The precise
conditions are found in the GNU General Public License that comes with
Emacs and also appears in this manual@footnote{This manual is itself
covered by the GNU Free Documentation License.  This license is
similar in spirit to the General Public License, but is more suitable
for documentation.  @xref{GNU Free Documentation License}.}.
@xref{Copying}.

One way to get a copy of GNU Emacs is from someone else who has it.
You need not ask for our permission to do so, or tell anyone else;
just copy it.  If you have access to the Internet, you can get the
latest distribution version of GNU Emacs by anonymous FTP; see
@url{https://www.gnu.org/software/emacs} on our website for more
information.

You may also receive GNU Emacs when you buy a computer.  Computer
manufacturers are free to distribute copies on the same terms that apply to
everyone else.  These terms require them to give you the full sources,
including whatever changes they may have made, and to permit you to
redistribute the GNU Emacs received from them under the usual terms of the
General Public License.  In other words, the program must be free for you
when you get it, not just free for the manufacturer.

@node Intro
@unnumbered Introduction

  You are reading about GNU Emacs, the GNU incarnation of the
advanced, self-documenting, customizable, extensible editor Emacs.
(The @samp{G} in
@c Workaround makeinfo 4 bug.
@c https://lists.gnu.org/r/bug-texinfo/2004-08/msg00009.html
@iftex
@acronym{GNU, @acronym{GNU}'s Not Unix}
@end iftex
@ifnottex
@acronym{GNU, GNU's Not Unix}
@end ifnottex
is not silent.)

  We call Emacs @dfn{advanced} because it can do much more than simple
insertion and deletion of text.  It can control subprocesses, indent
programs automatically, show multiple files at once, edit remote files
like they were local files, and more.  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 use special
commands, known as @dfn{help commands}, to find out what your options
are, or to find out what any command does, or to find all the
commands that pertain to a given topic.  @xref{Help}.

  @dfn{Customizable} means that you can easily alter the behavior of
Emacs commands in simple ways.  For instance, 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}).  To take another 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 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.
