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

		115	The following will add an entry C<a to b> that transforms all C<a>s in

		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.

		188
		189	To expand the example above to typical perl error messages ("XXX at
		190	FILENAME line YYY."), you need a slightly more elaborate solution:
		191
		192	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		193	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		194
		195	The first line tells the selection code to treat the unchanging part of
		196	every error message as a selection pattern, and the second line transforms
		197	the message into vi commands to load the file.
		198
		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.

		217	=item automove-background
		218
		219	This is basically a one-line extension that dynamically changes the background pixmap offset
		220	to the window position, in effect creating the same effect as pseudo transparency with
		221	a custom pixmap. No scaling is supported in this mode. Exmaple:

		240
		241	=item selection-pastebin
		242
		243	This is a little rarely useful extension that Uploads the selection as
		244	textfile to a remote site (or does other things). (The implementation is
		245	not currently secure for use in a multiuser environment as it writes to
		246	F</tmp> directly.).
		247
		248	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		249	i.e.
		250
		251	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		252
		253	Pressing this combination runs a command with C<%> replaced by the name of
		254	the textfile. This command can be set via a resource:
		255
		256	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		257
		258	And the default is likely not useful to anybody but the few people around
		259	here :)
		260
		261	The name of the textfile is the hex encoded md5 sum of the selection, so
		262	the same content should lead to the same filename.
		263
		264	After a successful upload the selection will be replaced by the text given
		265	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		266	for the filename):
		267
