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

		102	It's sole argument is the popup menu, which can be modified. The selection
		103	is in C<$_>, which can be used to decide wether to add something or not.

		167	=item readline
		168
		169	A support package that tries to make editing with readline easier. At the
		170	moment, it reacts to clicking with the left mouse button by trying to
		171	move the text cursor to this position. It does so by generating as many
		172	cursor-left or cursor-right keypresses as required (the this only works
		173	for programs that correctly support wide characters).
		174
		175	It only works when clicking into the same line (possibly extended over
		176	multiple rows) as the text cursor and on the primary screen, to reduce the
		177	risk of misinterpreting. The normal selection isn't disabled, so quick
		178	successive clicks might interfere with selection creation in harmless
		179	ways.
		180
		181	=item tabbed
		182
		183	This transforms the terminal into a tabbar with additional terminals, that
		184	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		185	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		186	button per tab.
		187
		188	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		189	B<Shift-Right> will switch to the tab left or right of the current one,
		190	while B<Shift-Down> creates a new tab.

		199	=item automove-background
		200
		201	This is basically a one-line extension that dynamically changes the background pixmap offset
		202	to the window position, in effect creating the same effect as pseudo transparency with
		203	a custom pixmap. No scaling is supported in this mode. Exmaple:

		223	=item selection-pastebin
		224
		225	This is a little rarely useful extension that Uploads the selection as
		226	textfile to a remote site (or does other things). (The implementation is
		227	not currently secure for use in a multiuser environment as it writes to
		228	F</tmp> directly.).
		229
		230	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		231	i.e.
		232
		233	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		234
		235	Pressing this combination runs a command with C<%> replaced by the name of
		236	the textfile. This command can be set via a resource:
		237
		238	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		239
		240	And the default is likely not useful to anybody but the few people around
		241	here :)
		242
		243	The name of the textfile is the hex encoded md5 sum of the selection, so
		244	the same content should lead to the same filename.
		245
		246	After a successful upload the selection will be replaced by the text given
		247	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		248	for the filename):
		249
		250	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
