77<p>This section describes the extensiosn delivered with this version. You can
78find them in <em>/opt/rxvt/lib/urxvt/perl/</em>.</p>
79<p>You can activate them like this:</p>
80<pre>

82<dl>
83<dt><strong><a name="item_selection">selection (enabled by default)</a></strong><br />
84</dt>
85<dd>
86Intelligent selection. This extension tries to be more intelligent when
87the user extends selections (double-click). Right now, it tries to select
88urls and complete shell-quoted arguments, which is very convenient, too,
89if your <em>ls</em> supports <code>--quoting-style=shell</code>.
90</dd>

816</dt>
817<dd>
818Returns the negative row number of the topmost line. Minimum value is
819<code>0</code>, which displays the normal terminal contents. Larger values scroll

822<p></p>
823<dt><strong><a name="item_want_refresh">$term-&gt;want_refresh</a></strong><br />

827compare the on-screen display with its stored representation. If they
828differ, it redraws the differences.
829</dd>
830<dd>

835</dt>
836<dd>
837Returns the text of the entire row with number <code>$row_number</code>. Row <code>0</code>
838is the topmost terminal line, row <code>$term-&gt;$ncol-1</code> is the bottommost
839terminal line. The scrollback buffer starts at line <code>-1</code> and extends to
840line <a href="#item_nsaved"><code>-$term-&gt;nsaved</code></a>. Nothing will be returned if a nonexistent line
841is requested.
842</dd>
843<dd>
844<p>If <code>$new_text</code> is specified, it will replace characters in the current
845line, starting at column <code>$start_col</code> (default <code>0</code>), which is useful
846to replace only parts of a line. The font index in the rendition will
847automatically be updated.</p>
848</dd>
849<dd>
850<p><a href="#item__24text"><code>$text</code></a> is in a special encoding: tabs and wide characters that use more
851than one cell when displayed are padded with urxvt::NOCHAR characters

853that do not fit into the normal tetx encoding will be replaced with
854characters in the private use area.</p>

856<dd>
857<p>You have to obey this encoding when changing text. The advantage is
858that <code>substr</code> and similar functions work on screen cells and not on

891Returns true if the row is part of a multiple-row logical ``line'' (i.e.
