		98	Other extensions can extend this popup menu by pushing a code reference
		99	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
		100	popup is displayed.
		101
		102	It's sole argument is the popup menu, which can be modified. The selection
		103	is in C<$_>, which can be used to decide wether to add something or not.
		104	It should either return nothing or a string and a code reference. The
		105	string will be used as button text and the code reference will be called
		106	when the button gets activated and should transform C<$_>.
		107
		108	The following will add an entry C<a to b> that transforms all C<a>s in
		109	the selection to C<b>s, but only if the selection currently contains any

		154
		155	Of course, this can be modified to suit your needs and your editor :)
		156
		157	To expand the example above to typical perl error messages ("XXX at
		158	FILENAME line YYY."), you need a slightly more elaborate solution:
		159
		160	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		161	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		162
		163	The first line tells the selection code to treat the unchanging part of
		164	every error message as a selection pattern, and the second line transforms
		165	the message into vi commands to load the file.
		166
		167	=item tabbed
		168
		169	This transforms the terminal into a tabbar with additional terminals, that
		170	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		171	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		172	button per tab.
		173
		174	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		175	B<Shift-Right> will switch to the tab left or right of the current one,
		176	while B<Shift-Down> creates a new tab.

		185	=item automove-background
		186
		187	This is basically a one-line extension that dynamically changes the background pixmap offset
		188	to the window position, in effect creating the same effect as pseudo transparency with
		189	a custom pixmap. No scaling is supported in this mode. Exmaple:

		209	=item selection-pastebin
		210
		211	This is a little rarely useful extension that Uploads the selection as
		212	textfile to a remote site (or does other things). (The implementation is
		213	not currently secure for use in a multiuser environment as it writes to
		214	F</tmp> directly.).
		215
		216	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		217	i.e.
		218
		219	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		220
		221	Pressing this combination runs a command with C<%> replaced by the name of
		222	the textfile. This command can be set via a resource:
		223
		224	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		225
		226	And the default is likely not useful to anybody but the few people around
		227	here :)
		228
		229	The name of the textfile is the hex encoded md5 sum of the selection, so
		230	the same content should lead to the same filename.
		231
		232	After a successful upload the selection will be replaced by the text given
		233	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		234	for the filename):
		235
		236	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
