		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 tty is in ICANON state.
		145
		146	=item - the text cursor is visible.
		147
		148	=item - the primary screen is currently being displayed.
		149
		150	=item - the mouse is on the same (multi-row-) line as the text cursor.
		151
		152	=back
		153
		154	The normal selection mechanism isn't disabled, so quick successive clicks
		155	might interfere with selection creation in harmless ways.

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

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

		233
		234	=item selection-pastebin
		235
		236	This is a little rarely useful extension that Uploads the selection as
		237	textfile to a remote site (or does other things). (The implementation is
		238	not currently secure for use in a multiuser environment as it writes to
		239	F</tmp> directly.).
		240
		241	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		242	i.e.
		243
		244	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		245
		246	Pressing this combination runs a command with C<%> replaced by the name of
		247	the textfile. This command can be set via a resource:
		248
		249	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		250
		251	And the default is likely not useful to anybody but the few people around
		252	here :)
		253
		254	The name of the textfile is the hex encoded md5 sum of the selection, so
		255	the same content should lead to the same filename.
		256
		257	After a successful upload the selection will be replaced by the text given
		258	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		259	for the filename):
		260
		261	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
