		156	=item readline (enabled by default)
		157
		158	A support package that tries to make editing with readline easier. At
		159	the moment, it reacts to clicking shift-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:

		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>

		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.

		253	You enable it by specifying this extension and a preedit style of

		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:

		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

		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).
