<h2 class="chapter">16 Viewing Message Threads</h2>
<p><a name="index-threading-1786"></a>
MH-E groups messages by <dfn>threads</dfn> which are messages that are part
of the same discussion and usually all have the same `<samp><span class="samp">Subject:</span></samp>'
header field. Other ways to organize messages in a folder include
limiting (see <a href="Limits.html#Limits">Limits</a>) or using full-text indexed searches
(see <a href="Searching.html#Searching">Searching</a>).
<p><a name="index-root_002c-in-threads-1787"></a><a name="index-siblings_002c-in-threads-1788"></a><a name="index-ancestor_002c-in-threads-1789"></a>
A thread begins with a single message called a <dfn>root</dfn>. All replies
to the same message are <dfn>siblings</dfn> of each other. Any message that
has replies to it is an <dfn>ancestor</dfn> of those replies.
<p>There are several commands that you can use to navigate and operate on
threads.

The `<samp><span class="samp">mh-thread</span></samp>' customization group contains one option.
<dl>
<dt><code>mh-show-threads-flag</code><a name="index-mh_002dshow_002dthreads_002dflag-1806"></a><dd>On means new folders start in threaded mode (default: `<samp><span class="samp">off</span></samp>').

Threading large number of messages can be time consuming so the option
<code>mh-show-threads-flag</code> is turned off by default. If you turn on
this option, then threading will be done only if the number of
messages being threaded is less than <code>mh-large-folder</code>. In any
event, threading can be turned on (and off) with the command <kbd>T t</kbd>
(<code>mh-toggle-threads</code>).
<p><a name="index-mh_002dthread_002dancestor-1811"></a><a name="index-mh_002dthread_002dnext_002dsibling-1812"></a><a name="index-mh_002dthread_002dprevious_002dsibling-1813"></a><a name="index-T-n-1814"></a><a name="index-T-p-1815"></a><a name="index-T-u-1816"></a>
There are a few commands to help you navigate threads. If you do not
care for the way a particular thread has turned, you can move up the
chain of messages with the command <kbd>T u</kbd>
(<code>mh-thread-ancestor</code>. At any point you can use <kbd>T n</kbd>
(<code>mh-thread-next-sibling</code> or <kbd>T p</kbd>
(<code>mh-thread-previous-sibling</code>) to jump to the next or previous
sibling, skipping the sub-threads. The command <kbd>T u</kbd> can also take
a prefix argument to jump to the message that started everything.
<p><a name="index-mh_002ddelete_002dsubject_002dor_002dthread-1817"></a><a name="index-mh_002dthread_002ddelete-1818"></a><a name="index-mh_002dthread_002drefile-1819"></a><a name="index-k-1820"></a><a name="index-T-d-1821"></a><a name="index-T-o-1822"></a>
There are threaded equivalents for the commands that delete and refile
messages. For example, <kbd>T o</kbd> (<code>mh-thread-refile</code>) refiles the
current message and all its children. Similarly, the command <kbd>T d</kbd>
(<code>mh-thread-delete</code>) deletes the current message and all its
children. These commands do not refile or delete sibling messages.
See <a href="Navigating.html#Navigating">Navigating</a>, for a description of the similar command <kbd>k</kbd>
(<code>mh-delete-subject-or-thread</code>).
<p><a name="index-mh_002dlarge_002dfolder-1823"></a>
If you find that threading is too slow, it may be that you have
<code>mh-large-folder</code> set too high. Also, threading is one of the few
features of MH-E that really benefits from compiling. If you haven't
compiled MH-E, I encourage you to do so<a rel="footnote" href="#fn-1" name="fnd-1"><sup>1</sup></a>.
<div class="footnote">
<hr>
<h4>Footnotes</h4><p class="footnote"><small>[<a name="fn-1" href="#fnd-1">1</a>]</small> If you're not sure if
MH-E has been byte-compiled, you could try running `<samp><span class="samp">locate
mh-thread.elc</span></samp>' or otherwise find MH-E on your system and ensure that
<samp><span class="file">mh-thread.elc</span></samp> exists. If you have multiple versions and you
find that one is compiled but the other is not, then go into your
`<samp><span class="samp">*scratch*</span></samp>' buffer in Emacs, enter <kbd>load-path C-j</kbd>, and
ensure that the byte-compiled version appears first in the
<code>load-path</code>. If you find that MH-E is not compiled and you
installed MH-E yourself, please refer to the installation directions
in the file <samp><span class="file">README</span></samp> in the distribution.</p>
