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

		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

		132	=item readline (enabled by default)
		133
		134	A support package that tries to make editing with readline easier. At the
		135	moment, it reacts to clicking with the left mouse button by trying to
		136	move the text cursor to this position. It does so by generating as many
		137	cursor-left or cursor-right keypresses as required (the this only works
		138	for programs that correctly support wide characters).
		139
		140	To avoid too many false positives, this is only done when:
		141
		142	=over 4
		143
		144	=item - the mouse is on the same (multi-row-) line as the text cursor.
		145
		146	=item - the primary screen is currently being displayed.
		147
		148	=item - the text cursor is visible.
		149
		150	=back
		151
		152	The normal selection mechanism isn't disabled, so quick successive clicks
		153	might interfere with selection creation in harmless ways.

		177
		178	Of course, this can be modified to suit your needs and your editor :)
		179
		180	To expand the example above to typical perl error messages ("XXX at
		181	FILENAME line YYY."), you need a slightly more elaborate solution:
		182
		183	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		184	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		185
		186	The first line tells the selection code to treat the unchanging part of
		187	every error message as a selection pattern, and the second line transforms
		188	the message into vi commands to load the file.
		189
		190	=item tabbed
		191
		192	This transforms the terminal into a tabbar with additional terminals, that
		193	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		194	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		195	button per tab.
		196
		197	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		198	B<Shift-Right> will switch to the tab left or right of the current one,
		199	while B<Shift-Down> creates a new tab.

		208	=item automove-background
		209
		210	This is basically a one-line extension that dynamically changes the background pixmap offset
		211	to the window position, in effect creating the same effect as pseudo transparency with
		212	a custom pixmap. No scaling is supported in this mode. Exmaple:

		231
		232	=item selection-pastebin
		233
		234	This is a little rarely useful extension that Uploads the selection as
		235	textfile to a remote site (or does other things). (The implementation is
		236	not currently secure for use in a multiuser environment as it writes to
		237	F</tmp> directly.).
		238
		239	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		240	i.e.
		241
		242	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		243
		244	Pressing this combination runs a command with C<%> replaced by the name of
		245	the textfile. This command can be set via a resource:
		246
		247	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		248
		249	And the default is likely not useful to anybody but the few people around
		250	here :)
		251
		252	The name of the textfile is the hex encoded md5 sum of the selection, so
		253	the same content should lead to the same filename.
		254
		255	After a successful upload the selection will be replaced by the text given
		256	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		257	for the filename):
		258
		259	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
