Instead of using -different “modes”, 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 -“in Emacs”.</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> - -<div class="INFORMALFIGURE"><a id="AEN5971" name="AEN5971"></a> -<p><img src="emacs/emacs.png" /></p> -</div> - -<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> -</div> -</div> -</div> - -<div class="NAVFOOTER"> -<hr align="LEFT" width="100%" /> -<table summary="Footer navigation table" width="100%" border="0" cellpadding="0" -cellspacing="0"> -<tr> -<td width="33%" align="left" valign="top"><a href="vi-keys.html" -accesskey="P">Prev</a></td> -<td width="34%" align="center" valign="top"><a href="index.html" -accesskey="H">Home</a></td> -<td width="33%" align="right" valign="top"><a href="emacs-buffers.html" -accesskey="N">Next</a></td> -</tr> - -<tr> -<td width="33%" align="left" valign="top">Vi Keys</td> -<td width="34%" align="center" valign="top"> </td> -<td width="33%" align="right" valign="top">Buffers</td> -</tr> -</table> -</div> -</body> -</html> - |
