		156	=item readline (enabled by default)
		157
		158	A support package that tries to make editing with readline easier. At the
		159	moment, it reacts to clicking with the left mouse button by trying to
		160	move the text cursor to this position. It does so by generating as many
		161	cursor-left or cursor-right keypresses as required (the this only works
		162	for programs that correctly support wide characters).
		163
		164	To avoid too many false positives, this is only done when:
		165
		166	=over 4

		216	=item tabbed
		217
		218	This transforms the terminal into a tabbar with additional terminals, that
		219	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		220	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		221	button per tab.
		222
		223	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		224	B<Shift-Right> will switch to the tab left or right of the current one,
		225	while B<Shift-Down> creates a new tab.
		226
		227	The tabbar itself can be configured similarly to a normal terminal, but
		228	with a resource class of C<URxvt.tabbed>. In addition, it supports the
		229	following four resources (shown with defaults):
		230
		231	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
		232	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
		233	URxvt.tabbed.tab-fg: <colour-index, default 0>
		234	URxvt.tabbed.tab-bg: <colour-index, default 1>
		235

		237	indices.

150		245
		246	=item xim-onthespot
		247
		248	This (experimental) perl extension implements OnTheSpot editing. It does
		249	not work perfectly, and some input methods don't seem to work well with
		250	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		251	kinput2.
		252
		253	You enable it by specifying this extension and a preedit style of
		254	C<OnTheSpot>, i.e.:
		255
		256	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		257
		258	=item automove-background
		259
		260	This is basically a one-line extension that dynamically changes the background pixmap offset
		261	to the window position, in effect creating the same effect as pseudo transparency with
		262	a custom pixmap. No scaling is supported in this mode. Exmaple:

		275
		276	=item remote-clipboard
		277
		278	Somewhat of a misnomer, this extension adds two menu entries to the
		279	selection popup that allows one ti run external commands to store the
		280	selection somewhere and fetch it again.
		281
		282	We use it to implement a "distributed selection mechanism", which just
		283	means that one command uploads the file to a remote server, and another
		284	reads it.
		285
		286	The commands can be set using the C<URxvt.remote-selection.store> and
		287	C<URxvt.remote-selection.fetch> resources. The first should read the
		288	selection to store from STDIN (always in UTF-8), the second should provide
		289	the selection data on STDOUT (also in UTF-8).
		290
		291	The defaults (which are likely useless to you) use rsh and cat:
		292
		293	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		294	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		295
		296	=item selection-pastebin
		297
		298	This is a little rarely useful extension that Uploads the selection as
		299	textfile to a remote site (or does other things). (The implementation is
		300	not currently secure for use in a multiuser environment as it writes to
		301	F</tmp> directly.).
		302
		303	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		304	i.e.
		305
		306	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		307
		308	Pressing this combination runs a command with C<%> replaced by the name of
		309	the textfile. This command can be set via a resource:
		310
		311	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		312
		313	And the default is likely not useful to anybody but the few people around
		314	here :)
		315
		316	The name of the textfile is the hex encoded md5 sum of the selection, so
		317	the same content should lead to the same filename.
		318
		319	After a successful upload the selection will be replaced by the text given
		320	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		321	for the filename):
		322
		323	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
