		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.

		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.

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

		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>

		252	=item xim-onthespot
		253
		254	This (experimental) perl extension implements OnTheSpot editing. It does
		255	not work perfectly, and some input methods don't seem to work well with
		256	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		257	kinput2.
		258
		259	You enable it by specifying this extension and a preedit style of
		260	C<OnTheSpot>, i.e.:
		261
		262	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		263
		264	=item kuake<hotkey>
		265
		266	A very primitive quake-console-like extension. It was inspired by a
		267	description of how the programs C<kuake> and C<yakuake> work: Whenever the
		268	user presses a global accelerator key (by default C<F10>), the terminal
		269	will show or hide itself. Another press of the accelerator key will hide
		270	or show it again.
		271
		272	Initially, the window will not be shown when using this extension.
		273
		274	This is useful if you need a single terminal thats not using any desktop
		275	space most of the time but is quickly available at the press of a key.
		276
		277	The accelerator key is grabbed regardless of any modifiers, so this
		278	extension will actually grab a physical key just for this function.
		279
		280	If you want a quake-like animation, tell your window manager to do so
		281	(fvwm can do it).
		282
		283	=item automove-background
		284
		285	This is basically a very small extension that dynamically changes the
		286	background pixmap offset to the window position, in effect creating the
		287	same effect as pseudo transparency with a custom pixmap. No scaling is
		288	supported in this mode. Example:
		289

		307
		308	We use it to implement a "distributed selection mechanism", which just
		309	means that one command uploads the file to a remote server, and another

		311
		312	The commands can be set using the C<URxvt.remote-selection.store> and
		313	C<URxvt.remote-selection.fetch> resources. The first should read the
		314	selection to store from STDIN (always in UTF-8), the second should provide
		315	the selection data on STDOUT (also in UTF-8).
		316
		317	The defaults (which are likely useless to you) use rsh and cat:
