		159	The regex defaults to "(?i)", resulting in a case-insensitive search. To

		161	or simply use an uppercase character which removes the "(?i)" prefix.
		162
		163	See L<perlre> for more info about perl regular expression syntax.
		164
		165	=item readline (enabled by default)
		166
		167	A support package that tries to make editing with readline easier. At
		168	the moment, it reacts to clicking shift-left mouse button by trying to
		169	move the text cursor to this position. It does so by generating as many
		170	cursor-left or cursor-right keypresses as required (this only works
		171	for programs that correctly support wide characters).
		172
		173	To avoid too many false positives, this is only done when:
		174
		175	=over 4
		176
		177	=item - the tty is in ICANON state.
		178
		179	=item - the text cursor is visible.
		180
		181	=item - the primary screen is currently being displayed.
		182
		183	=item - the mouse is on the same (multi-row-) line as the text cursor.
		184
		185	=back
		186
		187	The normal selection mechanism isn't disabled, so quick successive clicks
		188	might interfere with selection creation in harmless ways.

130		212
131	=item mark-urls	213	Of course, this can be modified to suit your needs and your editor :)
132		214
		215	To expand the example above to typical perl error messages ("XXX at
		216	FILENAME line YYY."), you need a slightly more elaborate solution:
		217
		218	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		219	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		220
		221	The first line tells the selection code to treat the unchanging part of
		222	every error message as a selection pattern, and the second line transforms
		223	the message into vi commands to load the file.
		224
		225	=item tabbed
		226
		227	This transforms the terminal into a tabbar with additional terminals, that
		228	is, it implements what is commonly referred to as "tabbed terminal". The topmost line
		229	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		230	button per tab.
		231
		232	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		233	B<Shift-Right> will switch to the tab left or right of the current one,
		234	while B<Shift-Down> creates a new tab.
		235
		236	The tabbar itself can be configured similarly to a normal terminal, but
		237	with a resource class of C<URxvt.tabbed>. In addition, it supports the
		238	following four resources (shown with defaults):
		239
		240	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
		241	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
		242	URxvt.tabbed.tab-fg: <colour-index, default 0>
		243	URxvt.tabbed.tab-bg: <colour-index, default 1>
		244
		245	See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
		246	indices.
		247
		248	=item matcher
		249
133	Uses per-line display filtering (C<on_line_update>) to underline urls and	250	Uses per-line display filtering (C<on_line_update>) to underline text
134	make them clickable. When middle-clicked, the program specified in the	251	matching a certain pattern and make it clickable. When clicked with the
135	resource C<urlLauncher> (default C<x-www-browser>) will be started with	252	mouse button specified in the C<matcher.button> resource (default 2, or
136	the URL as first argument.	253	middle), the program specified in the C<matcher.launcher> resource
		254	(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
		255	with the matched text as first argument. The default configuration is
		256	suitable for matching URLs and launching a web browser, like the
		257	former "mark-urls" extension.
		258
		259	The default pattern to match URLs can be overridden with the
		260	C<matcher.pattern.0> resource, and additional patterns can be specified
		261	with numbered patterns, in a manner similar to the "selection" extension.
		262	The launcher can also be overridden on a per-pattern basis.
		263
		264	It is possible to activate the most recently seen match from the keyboard.
		265	Simply bind a keysym to "perl:matcher" as seen in the example below.
		266
		267	Example configuration:
		268
		269	URxvt.perl-ext: default,matcher
		270	URxvt.urlLauncher: sensible-browser
		271	URxvt.keysym.C-Delete: perl:matcher
		272	URxvt.matcher.button: 1
		273	URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
		274	URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$)
		275	URxvt.matcher.launcher.2: gvim +$2 $1
		276
		277	=item xim-onthespot
		278
		279	This (experimental) perl extension implements OnTheSpot editing. It does
		280	not work perfectly, and some input methods don't seem to work well with
		281	OnTheSpot editing in general, but it seems to work at least for SCIM and
		282	kinput2.
		283
		284	You enable it by specifying this extension and a preedit style of
		285	C<OnTheSpot>, i.e.:
		286
		287	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		288
		289	=item kuake<hotkey>
		290
		291	A very primitive quake-console-like extension. It was inspired by a
		292	description of how the programs C<kuake> and C<yakuake> work: Whenever the
		293	user presses a global accelerator key (by default C<F10>), the terminal
		294	will show or hide itself. Another press of the accelerator key will hide
		295	or show it again.
		296
		297	Initially, the window will not be shown when using this extension.
		298
		299	This is useful if you need a single terminal that is not using any desktop
		300	space most of the time but is quickly available at the press of a key.
		301
		302	The accelerator key is grabbed regardless of any modifiers, so this
		303	extension will actually grab a physical key just for this function.
		304
		305	If you want a quake-like animation, tell your window manager to do so
		306	(fvwm can do it).

		317
		318	=item remote-clipboard
		319
		320	Somewhat of a misnomer, this extension adds two menu entries to the
		321	selection popup that allows one to run external commands to store the
		322	selection somewhere and fetch it again.
		323
		324	We use it to implement a "distributed selection mechanism", which just
		325	means that one command uploads the file to a remote server, and another
		326	reads it.
		327
		328	The commands can be set using the C<URxvt.remote-selection.store> and
		329	C<URxvt.remote-selection.fetch> resources. The first should read the
		330	selection to store from STDIN (always in UTF-8), the second should provide
		331	the selection data on STDOUT (also in UTF-8).
		332
		333	The defaults (which are likely useless to you) use rsh and cat:
		334
		335	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		336	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		337
		338	=item selection-pastebin
		339
		340	This is a little rarely useful extension that Uploads the selection as
		341	textfile to a remote site (or does other things). (The implementation is
		342	not currently secure for use in a multiuser environment as it writes to
		343	F</tmp> directly.).
		344
		345	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		346	i.e.
		347
		348	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		349
		350	Pressing this combination runs a command with C<%> replaced by the name of
		351	the textfile. This command can be set via a resource:
		352
		353	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		354
		355	And the default is likely not useful to anybody but the few people around
		356	here :)
		357
		358	The name of the textfile is the hex encoded md5 sum of the selection, so
		359	the same content should lead to the same filename.
		360
		361	After a successful upload the selection will be replaced by the text given
		362	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		363	for the filename):
		364
		365	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
		366
		367	I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
		368	the double C</> characters as comment start. Use C<\057\057> instead,
		369	which works regardless of wether xrdb is used to parse the resource file
		370	or not.
