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

		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.

		176	=item - the text cursor is visible.
		177
		178	=item - the primary screen is currently being displayed.

		180	=item - the mouse is on the same (multi-row-) line as the text cursor.
		181
		182	=back

		185	might interfere with selection creation in harmless ways.

162	=item mark-urls	222	=item tabbed
163		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>

		243	indices.

		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/-]

		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).
