		156	The regex defaults to "(?i)", resulting in a case-insensitive search. To
		157	get a case-sensitive search you can delete this prefix using C<BackSpace>
		158	or simply use an uppercase character which removes the "(?i)" prefix.
		159
		160	See L<perlre> for more info about perl regular expression syntax.
		161
		162	=item readline (enabled by default)
		163
		164	A support package that tries to make editing with readline easier. At
		165	the moment, it reacts to clicking shift-left mouse button by trying to
		166	move the text cursor to this position. It does so by generating as many
		167	cursor-left or cursor-right keypresses as required (the this only works
		168	for programs that correctly support wide characters).
		169
		170	To avoid too many false positives, this is only done when:
		171
		172	=over 4
		173
		174	=item - the tty is in ICANON state.
		175
		176	=item - the text cursor is visible.
		177
		178	=item - the primary screen is currently being displayed.
		179
		180	=item - the mouse is on the same (multi-row-) line as the text cursor.
		181
		182	=back
		183
		184	The normal selection mechanism isn't disabled, so quick successive clicks
		185	might interfere with selection creation in harmless ways.

134	=item mark-urls	212	To expand the example above to typical perl error messages ("XXX at
		213	FILENAME line YYY."), you need a slightly more elaborate solution:
135		214
		215	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		216	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		217
		218	The first line tells the selection code to treat the unchanging part of
		219	every error message as a selection pattern, and the second line transforms
		220	the message into vi commands to load the file.
		221
		222	=item tabbed
		223
		224	This transforms the terminal into a tabbar with additional terminals, that
		225	is, it implements what is commonly referred to as "tabbed terminal". The topmost line
		226	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		227	button per tab.
		228
		229	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		230	B<Shift-Right> will switch to the tab left or right of the current one,
		231	while B<Shift-Down> creates a new tab.
		232
		233	The tabbar itself can be configured similarly to a normal terminal, but
		234	with a resource class of C<URxvt.tabbed>. In addition, it supports the
		235	following four resources (shown with defaults):
		236
		237	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
		238	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
		239	URxvt.tabbed.tab-fg: <colour-index, default 0>
		240	URxvt.tabbed.tab-bg: <colour-index, default 1>
		241
		242	See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
		243	indices.
		244

137	make them clickable. When middle-clicked, the program specified in the	248	matching a certain pattern and make it clickable. When clicked with the
138	resource C<urlLauncher> (default C<x-www-browser>) will be started with	249	mouse button specified in the C<matcher.button> resource (default 2, or
139	the URL as first argument.	250	middle), the program specified in the C<matcher.launcher> resource
		251	(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
		252	with the matched text as first argument. The default configuration is
		253	suitable for matching URLs and launching a web browser, like the
		254	former "mark-urls" extension.
		255
		256	The default pattern to match URLs can be overridden with the
		257	C<matcher.pattern.0> resource, and additional patterns can be specified
		258	with numbered patterns, in a manner similar to the "selection" extension.
		259	The launcher can also be overridden on a per-pattern basis.
		260
		261	Example configuration:
		262
		263	URxvt.perl-ext: default,matcher
		264	URxvt.urlLauncher: sensible-browser
		265	URxvt.matcher.button: 1
		266	URxvt.matcher.pattern.1: \\bwww\\.[\\w-]\\.[\\w./?&@#-]*[\\w/-]
		267	URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:\|$)
		268	URxvt.matcher.launcher.2: gvim +$2 $1
		269
		270	=item xim-onthespot
		271
		272	This (experimental) perl extension implements OnTheSpot editing. It does
		273	not work perfectly, and some input methods don't seem to work well with
		274	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		275	kinput2.
		276
		277	You enable it by specifying this extension and a preedit style of
		278	C<OnTheSpot>, i.e.:
		279
		280	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		281
		282	=item kuake<hotkey>
		283
		284	A very primitive quake-console-like extension. It was inspired by a
		285	description of how the programs C<kuake> and C<yakuake> work: Whenever the
		286	user presses a global accelerator key (by default C<F10>), the terminal
		287	will show or hide itself. Another press of the accelerator key will hide
		288	or show it again.
		289
		290	Initially, the window will not be shown when using this extension.
		291
		292	This is useful if you need a single terminal thats not using any desktop
		293	space most of the time but is quickly available at the press of a key.
		294
		295	The accelerator key is grabbed regardless of any modifiers, so this
		296	extension will actually grab a physical key just for this function.
		297
		298	If you want a quake-like animation, tell your window manager to do so
		299	(fvwm can do it).
		300
		301	=item automove-background
		302
		303	This is basically a very small extension that dynamically changes the
		304	background pixmap offset to the window position, in effect creating the
		305	same effect as pseudo transparency with a custom pixmap. No scaling is
		306	supported in this mode. Example:
		307
		308	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background

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