expressions, by using various operators to combine smaller expressions.

The fundamental building blocks are the regular expressions that match
a single character. Most characters, including all letters and digits,
are regular expressions that match themselves. Any metacharacter with
special meaning may be quoted by preceding it with a backslash.

+list. For example, the regular expression <span class="emphasis"><em>[0123456789]</em></span>
matches any single digit. A range of ASCII characters may be specified
by giving the first and last characters, separated by a hyphen
-``-''. Most metacharacters lose their special meaning inside
-lists. To include a literal ``]'' place it first in the list.
-Similarly, to include a literal ``^'' place it anywhere but first.
-Finally, to include a literal hyphen ``-'' place it last.

Certain named classes of characters are predefined. Character classes
-consist of ``[:'', a keyword denoting the class, and ``:]''.

Two additional special sequences can appear in character lists. These
apply to non-ASCII character sets, which can have single symbols (called
collating elements) that are represented with more than one character,
as well as several characters that are equivalent for collating or
sorting purposes:
-</p><p>
</p><div class="variablelist"><dl><dt><span class="term">Collating Symbols</span></dt><dd><p>
A collating symbol is a multi-character collating element enclosed in
-``[.'' and ``.]''. For example, if ``ch'' is a collating
-element, then <span class="bold"><strong>[[.ch.]]</strong></span> is a regexp that matches
-this collating element, while <span class="bold"><strong>[ch]</strong></span> is a regexp that
-matches either ``c'' or ``h''.
+“<span class="quote">[.</span>” and “<span class="quote">.]</span>”. For example, if “<span class="quote">ch</span>” is a collating
+element, then <span class="emphasis"><em>[[.ch.]]</em></span> is a regexp that matches

An equivalence class is a locale-specific name for a list of

Two regular expressions may be concatenated; the resulting regular
expression matches any string formed by concatenating two substrings
that respectively match the concatenated subexpressions.

parentheses to override these precedence rules.

+Mutt's parser for these patterns will strip one level of backslash (“<span class="quote">\</span>”),
which is normally used for quoting. If it is your intention to use a
backslash in the regular expression, you will need to use two backslashes

+instead (“<span class="quote">\\</span>”). You can force Mutt to treat <span class="emphasis"><em>EXPR</em></span> as a simple string
instead of a regular expression by using = instead of ˜ in the
-pattern name. For example, =b *.* will find all messages that contain
-the literal string '*.*'. Simple string matches are less powerful than

+the literal string “<span class="quote">*.*</span>”. Simple string matches are less powerful than
regular expressions but can be considerably faster. This is especially
true for IMAP folders, because string matches can be performed on the

+Mutt supports two versions of so called “<span class="quote">simple searches</span>”. These are
issued if the query entered for searching, limiting and similar
-operations does not seem to be a valid pattern (i.e. it does not contain
-one of these characters: ``~'', ``='' or ``%''). If the query is

+one of these characters: “<span class="quote">˜</span>”, “<span class="quote">=</span>” or “<span class="quote">%</span>”). If the query is
supposed to contain one of these special characters, they must be escaped
-by prepending a backslash (``\'').
+by prepending a backslash (“<span class="quote">\</span>”).
</p><p>
The first type is by checking whether the query string equals
-a keyword case-insensitively from <a href="advancedusage.html#tab-simplesearch-keywords" title="Table 4.2. Simple search keywords">Table 4.2, “Simple search keywords”</a>:
+a keyword case-insensitively from <a class="xref" href="advancedusage.html#tab-simplesearch-keywords" title="Table 4.5. Simple search keywords">Table 4.5, “Simple search keywords”</a>:
If that is the case, Mutt will use the shown pattern modifier instead.
If a keyword would conflict with your search keyword, you need to turn
it into a regular expression to avoid matching the keyword table. For
-example, if you want to find all messages matching ``<code class="literal">flag</code>''
-(using <a href="reference.html#simple-search" title="3.263. simple_search">$simple_search</a>,
-see below but not meaning flagged messages) simply search for
-``<code class="literal">[f]lag</code>''.

+pattern using <a class="link" href="reference.html#simple-search" title="3.236. simple_search">$simple_search</a>

Logical AND is performed by specifying more than one criterion. For
example:
-</p><p>
-
</p><pre class="screen">
~t mutt ~f elkins
</pre><p>
-
-</p><p>
-would select messages which contain the word ``mutt'' in the list of

+recipients <span class="emphasis"><em>and</em></span> that have the word “<span class="quote">elkins</span>” in the “<span class="quote">From</span>” header
field.
</p><p>
Mutt also recognizes the following operators to create more complex search
patterns:
-</p><p>
-
</p><div class="itemizedlist"><ul type="disc"><li><p>
-! -- logical NOT operator
+! — logical NOT operator
</p></li><li><p>

</p></li><li><p>
-() -- logical grouping operator
+() — logical grouping operator
</p></li></ul></div><p>
-
-</p><p>
Here is an example illustrating a complex search pattern. This pattern will
-select all messages which do not contain ``mutt'' in the ``To'' or ``Cc''
-field and which are from ``elkins''.
-</p><p>
-
-</p><pre class="screen">

Here is an example using white space in the regular expression (note

Sometimes it is desirable to perform an operation on a group of
messages all at once rather than one at a time. An example might be
to save messages to a mailing list to a separate folder, or to
delete all messages with a given subject. To tag all messages

-``shift-T'' by default. Or you can select individual messages by

Mutt has a few configuration options that make dealing with large
amounts of mail easier. The first thing you must do is to let Mutt
know what addresses you consider to be mailing lists (technically
this does not have to be a mailing list, but that is what it is most
often used for), and what lists you are subscribed to. This is
-accomplished through the use of the <a href="configuration.html#lists" title="11. Mailing lists">lists and subscribe</a> commands in your muttrc.

</p><p>
Now that Mutt knows what your mailing lists are, it can do several
things, the first of which is the ability to show the name of a list
through which you received a message (i.e., of a subscribed list) in
the <span class="emphasis"><em>index</em></span> menu display. This is useful to distinguish between
-personal and list mail in the same mailbox. In the <a href="reference.html#index-format" title="3.100. index_format">$index_format</a> variable, the escape ``%L''
-will return the string ``To <list>'' when ``list'' appears in the
-``To'' field, and ``Cc <list>'' when it appears in the ``Cc''
-field (otherwise it returns the name of the author).

+will print the string “<span class="quote">To <list></span>” when “<span class="quote">list</span>” appears in the
+“<span class="quote">To</span>” field, and “<span class="quote">Cc <list></span>” when it appears in the “<span class="quote">Cc</span>”

-Often times the ``To'' and ``Cc'' fields in mailing list messages
+Often times the “<span class="quote">To</span>” and “<span class="quote">Cc</span>” fields in mailing list messages
tend to get quite large. Most people do not bother to remove the

known mailing list addresses instead of all recipients (except as
specified by <code class="literal">Mail-Followup-To</code>, see below).
</p><p>
Mutt also supports the <code class="literal">Mail-Followup-To</code> header. When you send
a message to a list of recipients which includes one or several

Conversely, when group-replying or list-replying to a message which

than the author of the message. This can create problems when trying
to reply directly to the author in private, since most mail clients

-field. Mutt uses the <a href="reference.html#reply-to" title="3.242. reply_to">$reply_to</a>

variable to help decide which address to use. If set to <span class="emphasis"><em>ask-yes</em></span> or
<span class="emphasis"><em>ask-no</em></span>, you will be
prompted as to whether or not you would like to use the address given in
-the ``Reply-To'' field, or reply directly to the address given in the

used a threaded news client, this is the same concept. It makes dealing
with large volume mailing lists easier because you can easily delete
uninteresting threads and quickly find topics of value.
