		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.

		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

		243	indices.

150		251
		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
		290	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background

		301
		302	=item remote-clipboard
		303
		304	Somewhat of a misnomer, this extension adds two menu entries to the
		305	selection popup that allows one ti run external commands to store the
		306	selection somewhere and fetch it again.
		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
		310	reads it.
		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:
		318
		319	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		320	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		321
		322	=item selection-pastebin
		323
		324	This is a little rarely useful extension that Uploads the selection as
		325	textfile to a remote site (or does other things). (The implementation is
		326	not currently secure for use in a multiuser environment as it writes to
		327	F</tmp> directly.).
		328
		329	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		330	i.e.
		331
		332	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		333
		334	Pressing this combination runs a command with C<%> replaced by the name of
		335	the textfile. This command can be set via a resource:
		336
		337	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		338
		339	And the default is likely not useful to anybody but the few people around
		340	here :)
		341
		342	The name of the textfile is the hex encoded md5 sum of the selection, so
		343	the same content should lead to the same filename.
		344
		345	After a successful upload the selection will be replaced by the text given
		346	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		347	for the filename):
		348
		349	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
		350
		351	I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
		352	the double C</> characters as comment start. Use C<\057\057> instead,
		353	which works regardless of wether xrdb is used to parse the resource file
		354	or not.
