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:

62		84
63	Displays a digital clock using the built-in overlay.	85	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
		86	runtime.
		87
		88	=item selection-popup (enabled by default)
		89
		90	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
		91	text into various other formats/action (such as uri unescaping, perl
		92	evalution, web-browser starting etc.), depending on content.
		93
		94	=item searchable-scrollback<hotkey> (enabled by default)
		95
		96	Adds regex search functionality to the scrollback buffer, triggered
		97	by a hotkey (default: C<M-s>). While in search mode, normal terminal
		98	input/output is suspended and a regex is displayed at the bottom of the
		99	screen.
		100
		101	Inputting characters appends them to the regex and continues incremental
		102	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
		103	search upwards/downwards in the scrollback buffer, C<End> jumps to the
		104	bottom. C<Escape> leaves search mode and returns to the point where search
		105	was started, while C<Enter> or C<Return> stay at the current position and
		106	additionally stores the first match in the current line into the primary
		107	selection.
		108
		109	=item selection-autotransform
		110
		111	This selection allows you to do automatic transforms on a selection
		112	whenever a selection is made.
		113
		114	It works by specifying perl snippets (most useful is a single C<s///>
		115	operator) that modify C<$_> as resources:
		116
		117	URxvt.selection-autotransform.0: transform
		118	URxvt.selection-autotransform.1: transform
		119	...
		120
		121	For example, the following will transform selections of the form
		122	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		123	$word>:
		124
		125	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		126
		127	And this example matches the same,but replaces it with vi-commands you can
		128	paste directly into your (vi :) editor:
		129
		130	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
		131
		132	Of course, this can be modified to suit your needs and your editor :)
		133
		134	To expand the example above to typical perl error messages ("XXX at
		135	FILENAME line YYY."), you need a slightly more elaborate solution:
		136
		137	URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
		138	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
		139
		140	The first line tells the selection code to treat the unchanging part of
		141	every error message as a selection pattern, and the second line transforms
		142	the message into vi commands to load the file.

		224	=head2 Extension Objects
		225
		226	Very perl extension is a perl class. A separate perl object is created
		227	for each terminal and each extension and passed as the first parameter to
		228	hooks. So extensions can use their C<$self> object without having to think
		229	about other extensions, with the exception of methods and members that
		230	begin with an underscore character C<_>: these are reserved for internal
		231	use.
		232
		233	Although it isn't a C<urxvt::term> object, you can call all methods of the
		234	C<urxvt::term> class on this object.
		235
