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

		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 (the this only works
		171	for programs that correctly support wide characters).
		172
		173	To avoid too many false positives, this is only done when:

		183	=item - the mouse is on the same (multi-row-) line as the text cursor.
		184
		185	=back
		186

161	=item mark-urls	225	=item tabbed
162		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.

166	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	Example configuration:
		265
		266	URxvt.perl-ext: default,matcher
		267	URxvt.urlLauncher: sensible-browser
		268	URxvt.keysym.C-Delete: perl:matcher
		269	URxvt.matcher.button: 1
		270	URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
		271	URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:\|$)
		272	URxvt.matcher.launcher.2: gvim +$2 $1
		273
		274	=item xim-onthespot
		275
		276	This (experimental) perl extension implements OnTheSpot editing. It does
		277	not work perfectly, and some input methods don't seem to work well with
		278	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		279	kinput2.
		280
		281	You enable it by specifying this extension and a preedit style of
		282	C<OnTheSpot>, i.e.:
		283
		284	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		285
		286	=item kuake<hotkey>
		287
		288	A very primitive quake-console-like extension. It was inspired by a
		289	description of how the programs C<kuake> and C<yakuake> work: Whenever the
		290	user presses a global accelerator key (by default C<F10>), the terminal
		291	will show or hide itself. Another press of the accelerator key will hide
		292	or show it again.
		293
		294	Initially, the window will not be shown when using this extension.
		295
		296	This is useful if you need a single terminal thats not using any desktop
		297	space most of the time but is quickly available at the press of a key.
		298
		299	The accelerator key is grabbed regardless of any modifiers, so this
		300	extension will actually grab a physical key just for this function.
		301
		302	If you want a quake-like animation, tell your window manager to do so
		303	(fvwm can do it).
		304
		305	=item automove-background
		306
		307	This is basically a very small extension that dynamically changes the
		308	background pixmap offset to the window position, in effect creating the
		309	same effect as pseudo transparency with a custom pixmap. No scaling is
		310	supported in this mode. Example:
		311
		312	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
		313
		314	L<http://wiki.archlinux.org/index.php/Perl_Background_Rotation/Extensions>

		316	transparent background.

		327
		328	=item remote-clipboard
		329
		330	Somewhat of a misnomer, this extension adds two menu entries to the
		331	selection popup that allows one ti run external commands to store the
		332	selection somewhere and fetch it again.
		333
		334	We use it to implement a "distributed selection mechanism", which just
		335	means that one command uploads the file to a remote server, and another
		336	reads it.
		337
		338	The commands can be set using the C<URxvt.remote-selection.store> and
		339	C<URxvt.remote-selection.fetch> resources. The first should read the
		340	selection to store from STDIN (always in UTF-8), the second should provide
		341	the selection data on STDOUT (also in UTF-8).
		342
		343	The defaults (which are likely useless to you) use rsh and cat:
		344
		345	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		346	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		347
		348	=item selection-pastebin
		349
		350	This is a little rarely useful extension that Uploads the selection as
		351	textfile to a remote site (or does other things). (The implementation is
		352	not currently secure for use in a multiuser environment as it writes to
		353	F</tmp> directly.).
		354
		355	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		356	i.e.
		357
		358	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		359
		360	Pressing this combination runs a command with C<%> replaced by the name of
		361	the textfile. This command can be set via a resource:
		362
		363	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		364
		365	And the default is likely not useful to anybody but the few people around
		366	here :)
		367
		368	The name of the textfile is the hex encoded md5 sum of the selection, so
		369	the same content should lead to the same filename.
		370
		371	After a successful upload the selection will be replaced by the text given
		372	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		373	for the filename):
		374
		375	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
		376
		377	I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
		378	the double C</> characters as comment start. Use C<\057\057> instead,
		379	which works regardless of wether xrdb is used to parse the resource file
		380	or not.
