Some of the status flags can be turned on or off using

</p><div class="itemizedlist"><ul type="disc"><li><p>
<span class="bold"><strong>set-flag</strong></span> (default: w)

<span class="bold"><strong>clear-flag</strong></span> (default: W)

</p><p>
Furthermore, the following flags reflect who the message is addressed
to.  They can be customized with the
<a href="#to-chars" title="3.276.&#xA0;to_chars">$to_chars</a> variable.

By default, Mutt uses its builtin pager to display the body of messages.
The pager is very similar to the Unix program <span class="emphasis"><em>less</em></span> though not nearly as
featureful.
</p><p>

</p><div class="table"><a id="id2911793"></a><p class="title"><b>Table聽2.4.聽Most common pager keys</b></p><table summary="Most common pager keys" border="1"><colgroup><col /><col /></colgroup><thead><tr><th>Key</th><th>Description</th></tr></thead><tbody><tr><td>&lt;Return&gt;</td><td>go down one line</td></tr><tr><td>&lt;Space&gt;</td><td>display the next page (or next message if at the end of a message)</td></tr><tr><td>-</td><td>go back to the previous page</td></tr><tr><td>n</td><td>search for next match</td></tr><tr><td>S</td><td>skip beyond quoted text</td></tr><tr><td>T</td><td>toggle display of quoted text</td></tr><tr><td>?</td><td>show keybindings</td></tr><tr><td>/</td><td>search for a regular expression (pattern)</td></tr><tr><td>ESC /</td><td>search backwards for a regular expression</td></tr><tr><td>\</td><td>toggle search pattern coloring</td></tr><tr><td>^</td><td>jump to the top of the message</td></tr></tbody></table></div><p>

</p><p>
In addition, many of the functions from the <span class="emphasis"><em>index</em></span> are available in
the pager, such as <span class="emphasis"><em>delete-message</em></span> or <span class="emphasis"><em>copy-message</em></span> (this is one
advantage over using an external pager to view messages).
</p><p>
Also, the internal pager supports a couple other advanced features. For
one, it will accept and translate the ``standard'' nroff sequences for
bold and underline. These sequences are a series of either the letter,
backspace (^H), the letter again for bold or the letter, backspace,
``_'' for denoting underline. Mutt will attempt to display these
in bold and underline respectively if your terminal supports them. If
not, you can use the bold and underline <a href="#color" title="7.&#xA0;Using color and mono video attributes">color</a>
objects to specify a color or mono attribute for them.
</p><p>
Additionally, the internal pager supports the ANSI escape sequences for
