This manual documents the use and simple customization of the Emacs
editor. The reader is not expected to be a programmer; simple
customizations do not require programming skill. But the user who is not
interested in customizing can ignore the scattered customization hints.
This is primarily a reference manual, but can also be used as a
primer. For complete beginners, it is a good idea to start with the
on-line, learn-by-doing tutorial, before reading the manual. To run the
tutorial, start Emacs and type C-h t. This way you can learn
Emacs by using Emacs on a specially designed file which describes
commands, tells you when to try them, and then explains the results you
On first reading, just skim chapters one and two, 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 four you
should practice the commands there. The next few chapters describe
fundamental techniques and concepts that are used constantly. You need
to understand them thoroughly, experimenting with them if necessary.
Chapters 14 through 18 describe intermediate-level features that are
useful for all kinds of editing. Chapter 19 and following chapters
describe features that you may or may not want to use; read those
chapters when you need them
Read the Trouble chapter if Emacs does not seem to be working
properly. It explains how to cope with some common problems
(see section Dealing with Emacs Trouble), as well as when and how to report Emacs bugs
(see section Reporting Bugs).
To find the documentation on 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 on-line perusal with the Info program, which will
be the principle way of viewing documentation on-line in the GNU system.
Both the Info file and the Info program itself are distributed along
with GNU Emacs. The Info file and the printed book contain
substantially the same text and are generated from the same source
files, which are also distributed along 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, write for a copy of AI memo 519a, "Emacs, the Extensible,
Customizable Self-Documenting Display Editor", to Publications Department,
Artificial Intelligence Lab, 545 Tech Square, Cambridge, MA 02139, USA. At
last report they charge $2.25 per copy. Another useful publication is LCS
TM-165, "A Cookbook for an Emacs", by Craig Finseth, available from
Publications Department, Laboratory for Computer Science, 545 Tech Square,
Cambridge, MA 02139, USA. The price today is $3.
This edition of the manual is intended for use with GNU Emacs installed
on GNU and Unix systems. GNU Emacs can also be used on VMS, MS-DOS
(aka. MS-DOG) and Windows NT systems, but those systems have different
file name syntax and do not support all GNU Emacs features. We don't
try to describe VMS usage in this manual. See section MS-DOS Issues, for
information about using Emacs on MS-DOS.
GNU Emacs is free software; this means that everyone is free to
use it and free to redistribute it on 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 following this section.
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 any one 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 the file
`etc/FTP' in the Emacs distribution 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.
You can also order copies of GNU Emacs from the Free Software
Foundation, on various magnetic media or on CD-ROM. This is a
convenient and reliable way to get a copy; it is also a good way to help
fund our work. (The Foundation has always received most of its funds in
this way.) An order form is included at the end of manuals printed by
the Foundation. It is also included in the file `etc/ORDERS' in
the Emacs distribution. For further information, write to

The income from distribution fees goes to support the foundation's
purpose: the development of new free software, and improvements to our
existing programs including GNU Emacs.
If you find GNU Emacs useful, please send a donation to the
Free Software Foundation to support our work. Donations to the Free
Software Foundation are tax deductible. If you use GNU Emacs at your
workplace, suggest that the company make a donation. If company policy
is unsympathetic to the idea of donating to charity, you might instead
suggest ordering a CD-ROM from the Foundation occasionally, or
subscribing to periodic updates.
