237<p>To expand the example above to typical perl error messages (``XXX at

244</dd>
245<dd>
246<p>The first line tells the selection code to treat the unchanging part of
247every error message as a selection pattern, and the second line transforms
248the message into vi commands to load the file.</p>

251<dt><strong><a name="item_readline">readline</a></strong><br />
252</dt>
253<dd>
254A support package that tries to make editing with readline easier. At the
255moment, it reacts to clicking with the left mouse button by trying to
256move the text cursor to this position. It does so by generating as many
257cursor-left or cursor-right keypresses as required (the this only works
258for programs that correctly support wide characters).
259</dd>
260<dd>
261<p>It only works when clicking into the same line (possibly extended over
262multiple rows) as the text cursor and on the primary screen, to reduce the
263risk of misinterpreting. The normal selection isn't disabled, so quick
264successive clicks might interfere with selection creation in harmless
265ways.</p>

270<dd>
271This transforms the terminal into a tabbar with additional terminals, that
272is, it implements what is commonly refered to as ``tabbed terminal''. The topmost line
273displays a ``[NEW]'' button, which, when clicked, will add a new tab, followed by one
274button per tab.
275</dd>
276<dd>
277<p>Clicking a button will activate that tab. Pressing <strong>Shift-Left</strong> and
278<strong>Shift-Right</strong> will switch to the tab left or right of the current one,
279while <strong>Shift-Down</strong> creates a new tab.</p>

294This is basically a one-line extension that dynamically changes the background pixmap offset
295to the window position, in effect creating the same effect as pseudo transparency with
296a custom pixmap. No scaling is supported in this mode. Exmaple:

328This is a little rarely useful extension that Uploads the selection as
329textfile to a remote site (or does other things). (The implementation is
330not currently secure for use in a multiuser environment as it writes to
331<em>/tmp</em> directly.).

351here :)</p>
352</dd>
353<dd>
354<p>The name of the textfile is the hex encoded md5 sum of the selection, so
355the same content should lead to the same filename.</p>
356</dd>
357<dd>
358<p>After a successful upload the selection will be replaced by the text given
359in the <code>selection-pastebin-url</code> resource (again, the % is the placeholder
