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

		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.

		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 refered 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.

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 automove-background
		265
		266	This is basically a very small extension that dynamically changes the
		267	background pixmap offset to the window position, in effect creating the
		268	same effect as pseudo transparency with a custom pixmap. No scaling is
		269	supported in this mode. Exmaple:

		282
		283	=item remote-clipboard
		284
		285	Somewhat of a misnomer, this extension adds two menu entries to the
		286	selection popup that allows one ti run external commands to store the
		287	selection somewhere and fetch it again.
		288
		289	We use it to implement a "distributed selection mechanism", which just
		290	means that one command uploads the file to a remote server, and another
		291	reads it.
		292
		293	The commands can be set using the C<URxvt.remote-selection.store> and
		294	C<URxvt.remote-selection.fetch> resources. The first should read the
		295	selection to store from STDIN (always in UTF-8), the second should provide
		296	the selection data on STDOUT (also in UTF-8).
		297
		298	The defaults (which are likely useless to you) use rsh and cat:
		299
		300	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		301	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		302
		303	=item selection-pastebin
		304
		305	This is a little rarely useful extension that Uploads the selection as
		306	textfile to a remote site (or does other things). (The implementation is
		307	not currently secure for use in a multiuser environment as it writes to
		308	F</tmp> directly.).
		309
		310	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		311	i.e.
		312
		313	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		314
		315	Pressing this combination runs a command with C<%> replaced by the name of
		316	the textfile. This command can be set via a resource:
		317
		318	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		319
		320	And the default is likely not useful to anybody but the few people around
		321	here :)
		322
		323	The name of the textfile is the hex encoded md5 sum of the selection, so
		324	the same content should lead to the same filename.
		325
		326	After a successful upload the selection will be replaced by the text given
		327	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		328	for the filename):
		329
		330	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
