		105	Other extensions can extend this popup menu by pushing a code reference

		108
		109	It's sole argument is the popup menu, which can be modified. The selection
		110	is in C<$_>, which can be used to decide wether to add something or not.
		111	It should either return nothing or a string and a code reference. The

		139	=item readline (enabled by default)
		140
		141	A support package that tries to make editing with readline easier. At the
		142	moment, it reacts to clicking with the left mouse button by trying to
		143	move the text cursor to this position. It does so by generating as many
		144	cursor-left or cursor-right keypresses as required (the this only works
		145	for programs that correctly support wide characters).
		146
		147	To avoid too many false positives, this is only done when:
		148
		149	=over 4
		150
		151	=item - the tty is in ICANON state.
		152
		153	=item - the text cursor is visible.
		154
		155	=item - the primary screen is currently being displayed.
		156
		157	=item - the mouse is on the same (multi-row-) line as the text cursor.
		158
		159	=back
		160
		161	The normal selection mechanism isn't disabled, so quick successive clicks
		162	might interfere with selection creation in harmless ways.

		199	=item tabbed
		200
		201	This transforms the terminal into a tabbar with additional terminals, that
		202	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		203	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		204	button per tab.
		205
		206	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		207	B<Shift-Right> will switch to the tab left or right of the current one,
		208	while B<Shift-Down> creates a new tab.
		209
		210	The tabbar itself can be configured similarly to a normal terminal, but
		211	with a resource class of C<URxvt.tabbed>. In addition, it supports the
		212	following four resources (shown with defaults):
		213
		214	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
		215	URxvt.tabbed.tabbar-bg: <colour-index, default 0>

		229	=item xim-onthespot
		230
		231	This (experimental) perl extension implements OnTheSpot editing. It does
		232	not work perfectly, and some input methods don't seem to work well with
		233	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		234	kinput2.
		235
		236	You enable it by specifying this extension and a preedit style of

		240
		241	=item automove-background
		242
		243	This is basically a one-line extension that dynamically changes the background pixmap offset
		244	to the window position, in effect creating the same effect as pseudo transparency with
		245	a custom pixmap. No scaling is supported in this mode. Exmaple:

		264
		265	We use it to implement a "distributed selection mechanism", which just
		266	means that one command uploads the file to a remote server, and another

		268
		269	The commands can be set using the C<URxvt.remote-selection.store> and
		270	C<URxvt.remote-selection.fetch> resources. The first should read the
		271	selection to store from STDIN (always in UTF-8), the second should provide
		272	the selection data on STDOUT (also in UTF-8).
		273
