mutt-1.5.12 源代码。linux 下邮件接受的工具。

Your local system administrator may have altered the defaults for your site.
You can always type ``?'' in any menu to display the current bindings.
</p><p>
The first thing you need to do is invoke mutt, simply by typing mutt
at the command line.  There are various command-line options, see 
either the mutt man page or the <a href="#commandline" title="1.&#xA0;Command line options">reference</a>.

Information is presented in menus, very similar to ELM.  Here is a table
showing the common keys used to navigate menus in Mutt.
</p><p>

Mutt has a built-in line editor for inputting text, e.g. email
addresses or filenames. The keys used to manipulate text input are
very similar to those of Emacs. See the following table for a full
reference of available functions, their default key bindings, and
short descriptions.

You can remap the <span class="emphasis"><em>editor</em></span> functions using the
<a href="#bind" title="3.&#xA0;Changing the default key bindings">bind</a> command.  For example, to make
the <span class="emphasis"><em>Delete</em></span> key delete the character in front of
the cursor rather than under, you could use
</p><pre class="screen">
bind editor &lt;delete&gt; backspace
</pre></div><div class="sect2" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="editing-history"></a>2.2.聽History</h3></div></div></div><p>
The number of items in the built-in editor's history is controlled by
the <a href="#history" title="3.73.&#xA0;history">$history</a> variable. You may
cycle through them at an editor prompt by using the
<code class="literal">history-up</code> and/or <code class="literal">history-down</code>
commands.
</p><p>
Mutt maintains several distinct history lists, one for each of the
following categories:
</p><p>
</p><div class="itemizedlist"><ul type="disc"><li>muttrc commands</li><li>addresses and aliases</li><li>shell commands</li><li>filenames</li><li>patterns</li><li>everything else</li></ul></div><p>
</p><p>
Mutt automatically filters out repeated items from the history.  It
also mimics the behaviour of some shells by ignoring items starting
with a space.
</p><p>
The latter feature can be useful in macros to not clobber the history's
valuable entries with unwanted entries.

Similar to many other mail clients, there are two modes in which mail is
read in Mutt.  The first is the index of messages in the mailbox, which is
called the ``index'' in Mutt.  The second mode is the display of the
message contents.  This is called the ``pager.''
</p><p>
The next few sections describe the functions provided in each of these
modes.

In addition to who sent the message and the subject, a short summary of
the disposition of each message is printed beside the message number.
Zero or more of the following ``flags'' may appear, which mean:
</p><p>
</p><div class="variablelist"><dl><dt><span class="term">D</span></dt><dd><p>
message is deleted (is marked for deletion)
</p></dd><dt><span class="term">d</span></dt><dd><p>
