49	It also offers the following bindable event:	50	A double-click usually selects the word under the cursor, further clicks
		51	will enlarge the selection.
		52
		53	The selection works by trying to match a number of regexes and displaying
		54	them in increasing order of length. You can add your own regexes by
		55	specifying resources of the form:
		56
		57	URxvt.selection.pattern-0: perl-regex
		58	URxvt.selection.pattern-1: perl-regex
		59	...
		60
		61	The index number (0, 1...) must not have any holes, and each regex must
		62	contain at least one pair of capturing parentheses, which will be used for
		63	the match. For example, the followign adds a regex that matches everything
		64	between two vertical bars:
		65
		66	URxvt.selection.pattern-0: \\\|([^\|]+)\\\|
		67
		68	You can look at the source of the selection extension to see more
		69	interesting uses, such as parsing a line from beginning to end.
		70
		71	This extension also offers following bindable keyboard commands:

71	=item digital-clock	94	Other extensions can extend this popup menu by pushing a code reference onto
		95	C<@urxvt::ext::selection_popup::hook>, that is called whenever the popup is displayed.
72		96
73	Displays a digital clock using the built-in overlay.	97	It's sole argument is the popup menu, which can be modified. The selection
		98	is in C<$_>, which can be used to decide wether to add something or not.
		99	It should either return nothing or a string and a code reference. The
		100	string will be used as button text and the code reference will be called
		101	when the button gets activated and should transform C<$_>.
		102
		103	The following will add an entry C<a to b> that transforms all C<a>s in
		104	the selection to C<b>s, but only if the selection currently contains any
		105	C<a>s:
		106
		107	push urxvt::ext::selection_popup::hook, sub {
		108	/a/ ? ("a to be" => sub { s/a/b/g }
		109	: ()
		110	};
		111
		112	=item searchable-scrollback<hotkey> (enabled by default)
		113
		114	Adds regex search functionality to the scrollback buffer, triggered
		115	by a hotkey (default: C<M-s>). While in search mode, normal terminal
		116	input/output is suspended and a regex is displayed at the bottom of the
		117	screen.
		118
		119	Inputting characters appends them to the regex and continues incremental
		120	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
		121	search upwards/downwards in the scrollback buffer, C<End> jumps to the
		122	bottom. C<Escape> leaves search mode and returns to the point where search
		123	was started, while C<Enter> or C<Return> stay at the current position and
		124	additionally stores the first match in the current line into the primary
		125	selection.
		126
		127	=item selection-autotransform
		128
		129	This selection allows you to do automatic transforms on a selection
		130	whenever a selection is made.
		131
		132	It works by specifying perl snippets (most useful is a single C<s///>
		133	operator) that modify C<$_> as resources:
		134
		135	URxvt.selection-autotransform.0: transform
		136	URxvt.selection-autotransform.1: transform
		137	...
		138
		139	For example, the following will transform selections of the form
		140	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		141	$word>:
		142
		143	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		144
		145	And this example matches the same,but replaces it with vi-commands you can
		146	paste directly into your (vi :) editor:
		147
		148	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
		149
		150	Of course, this can be modified to suit your needs and your editor :)
		151
		152	To expand the example above to typical perl error messages ("XXX at
		153	FILENAME line YYY."), you need a slightly more elaborate solution:
		154
		155	URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
		156	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
		157
		158	The first line tells the selection code to treat the unchanging part of
		159	every error message as a selection pattern, and the second line transforms
		160	the message into vi commands to load the file.
74		161

		165	make them clickable. When middle-clicked, the program specified in the
		166	resource C<urlLauncher> (default C<x-www-browser>) will be started with
		167	the URL as first argument.
		168
		169	=item automove-background
		170
		171	This is basically a one-line extension that dynamically changes the background pixmap offset
		172	to the window position, in effect creating the same effect as pseudo transparency with
		173	a custom pixmap. No scaling is supported in this mode. Exmaple:

		193	=item selection-pastebin
		194
		195	This is a little rarely useful extension that Uploads the selection as
		196	textfile to a remote site (or does other things). (The implementation is
		197	not currently secure for use in a multiuser environment as it writes to
		198	F</tmp> directly.).
		199
		200	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		201	i.e.
		202
		203	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		204
		205	Pressing this combination runs a command with C<%> replaced by the name of
		206	the textfile. This command can be set via a resource:
		207
		208	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		209
		210	And the default is likely not useful to anybody but the few people around
		211	here :)
		212
		213	The name of the textfile is the hex encoded md5 sum of the selection, so
		214	the same content should lead to the same filename.
		215
		216	After a successful upload the selection will be replaced by the text given
		217	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		218	for the filename):
		219
		220	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

		262	=head2 Extension Objects
		263
		264	Very perl extension is a perl class. A separate perl object is created
		265	for each terminal and each extension and passed as the first parameter to
		266	hooks. So extensions can use their C<$self> object without having to think
		267	about other extensions, with the exception of methods and members that
		268	begin with an underscore character C<_>: these are reserved for internal
		269	use.
		270
		271	Although it isn't a C<urxvt::term> object, you can call all methods of the
		272	C<urxvt::term> class on this object.
		273
		274	It has the following methods and data members:
