-<p>While <tt class="COMMAND">vi</tt> (with its clones) is without a doubt the most
-ubiquitous editor on Unix-like systems, Emacs comes in a good second. Instead of using
-different &#8220;modes&#8221;, like <tt class="COMMAND">vi</tt> does, it uses <b
-class="KEYCAP">Control</b> and <b class="KEYCAP">Alt</b> key combinations to enter
-commands, in much the same way that you can use <b class="KEYCAP">Control</b> and <b
-class="KEYCAP">Alt</b> key combinations in a word processor and indeed in many other
-applications to execute certain functions. (Though it should be noted that the commands
-rarely correspond; so while many modern applications use <b class="KEYCAP">Ctrl</b>-<b
-class="KEYCAP">C</b>/ <b class="KEYCAP">X</b>/ <b class="KEYCAP">V</b> for copying,
-cutting and pasting, Emacs uses different keys and actually a somewhat different
-mechanism for this.)</p>
-
-<p>Also unlike <tt class="COMMAND">vi</tt>, which is an (excellent) editor and nothing
-more, Emacs is a program with near endless capabilities. Emacs is (for the most part)
-written in Lisp, which is a very powerful programming language that has the peculiar
-property that every program written in it is automatically a Lisp compiler of its own.
-This means that the user can extend Emacs, and in fact write completely new programs
-&#8220;in Emacs&#8221;.</p>
-
-<p>As a result, Emacs is not just an editor anymore. There are many add-on packages for
-Emacs available (many come with the program's source) that provide all sorts of
-functionality. Many of these are related to text editing, which is after all Emacs' basic
-task, but it doesn't stop there. There are for example several spreadsheet programs for
-Emacs, there are databases, games, mail and news clients (the top one being Gnus),
-etc.</p>
-
-<p>There are two main versions of Emacs: GNU Emacs (which is the version that comes with
-Slackware) and XEmacs. The latter is <span class="emphasis"><i
-class="EMPHASIS">not</i></span> a version for Emacs running under X. In fact, both Emacs
-and XEmacs run on the console as well as under X. XEmacs was once started as a project to
-tidy up the Emacs code. Currently, both versions are being actively developed, and there
-is in fact much interaction between the two development teams. For the present chapter,
-it is immaterial whether you use Emacs or XEmacs, the differences between them are not
-relevant to the normal user.</p>
-
-<div class="SECT1">
-<h1 class="SECT1"><a id="EMACS-STARTING" name="EMACS-STARTING">17.1 Starting
-emacs</a></h1>
-
-<p>Emacs can be started from the shell by simply typing <tt class="COMMAND">emacs</tt>.
-When you are running X, Emacs will (normally) come up with its own X window, usually with
-a menu bar at the top, where you can find the most important functions. On startup, Emacs
-will first show a welcome message, and then after a few seconds will drop you in the
-*scratch* buffer. (See <a href="emacs-buffers.html">Section 17.2</a>.)</p>

-
-<p>You can also start Emacs on an existing file by typing</p>
-
-<table border="0" bgcolor="#E0E0E0" width="100%">
-<tr>
-<td>
-<pre class="SCREEN">
-<samp class="PROMPT">%</samp> <kbd class="USERINPUT">emacs /etc/resolv.conf</kbd>
-</pre>
-</td>
-</tr>
-</table>
-
-<p>This will cause Emacs to load the specified file when it starts up, skipping the
-welcome message.</p>
-
-<div class="SECT2">
-<h2 class="SECT2"><a id="EMACS-COMMAND-KEYS" name="EMACS-COMMAND-KEYS">17.1.1 Command
-Keys</a></h2>
-
-<p>As mentioned above, Emacs uses <b class="KEYCAP">Control</b> and <b
-class="KEYCAP">Alt</b> combinations for commands. The usual convention is to write these
-with <b class="KEYCAP">C</b>-<b class="KEYCAP">letter</b> and <b class="KEYCAP">M</b>-<b
-class="KEYCAP">letter</b>, respectively. So <b class="KEYCAP">C</b>-<b
-class="KEYCAP">x</b> means <b class="KEYCAP">Control</b>+<b class="KEYCAP">x</b>, and <b
-class="KEYCAP">M</b>-<b class="KEYCAP">x</b> means <b class="KEYCAP">Alt</b>+<b
-class="KEYCAP">x</b>. (The letter <b class="KEYCAP">M</b> is used instead of A because
-originally the key was not the <b class="KEYCAP">Alt</b> key but the <b
-class="KEYCAP">Meta</b> key. The <b class="KEYCAP">Meta</b> key has all but disappeared
-from computer keyboards, and in Emacs the <b class="KEYCAP">Alt</b> key has taken over
-its function.)</p>
-
-<p>Many Emacs commands consist of sequences of keys and key combinations. For example, <b
-class="KEYCAP">C</b>-<b class="KEYCAP">x</b> <b class="KEYCAP">C</b>-<b
-class="KEYCAP">c</b> (that is <b class="KEYCAP">Control</b>-<b class="KEYCAP">x</b>
-followed by <b class="KEYCAP">Control</b>-<b class="KEYCAP">c</b> ) quits Emacs, <b
-class="KEYCAP">C</b>-<b class="KEYCAP">x</b> <b class="KEYCAP">C</b>-<b
-class="KEYCAP">s</b> saves the current file. Keep in mind that <b class="KEYCAP">C</b>-<b
-class="KEYCAP">x</b> <b class="KEYCAP">C</b>-<b class="KEYCAP">b</b> is <span
-class="emphasis"><i class="EMPHASIS">not</i></span> the same as <b
-class="KEYCAP">C</b>-<b class="KEYCAP">x</b> <b class="KEYCAP">b</b>. The former means <b
-class="KEYCAP">Control</b>-<b class="KEYCAP">x</b> followed by <b
-class="KEYCAP">Control</b>-<b class="KEYCAP">b</b>, while the latter means <b
-class="KEYCAP">Control</b>-<b class="KEYCAP">x</b> followed by just '<b
-class="KEYCAP">b</b>'.</p>
