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:

		90
		91	The % is the placeholder for the textfile. The name of the textfile is the hex encoded
		92	md5 sum of the selection.
		93	After an successful upload the selection will be replaced by the following url
		94	(the % is the placeholder for the filename):

73	Displays a digital clock using the built-in overlay.	113	Adds regex search functionality to the scrollback buffer, triggered
		114	by a hotkey (default: C<M-s>). While in search mode, normal terminal
		115	input/output is suspended and a regex is displayed at the bottom of the
		116	screen.
		117
		118	Inputting characters appends them to the regex and continues incremental
		119	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
		120	search upwards/downwards in the scrollback buffer, C<End> jumps to the
		121	bottom. C<Escape> leaves search mode and returns to the point where search
		122	was started, while C<Enter> or C<Return> stay at the current position and
		123	additionally stores the first match in the current line into the primary
		124	selection.
		125
		126	=item selection-autotransform
		127
		128	This selection allows you to do automatic transforms on a selection
		129	whenever a selection is made.
		130
		131	It works by specifying perl snippets (most useful is a single C<s///>
		132	operator) that modify C<$_> as resources:
		133
		134	URxvt.selection-autotransform.0: transform
		135	URxvt.selection-autotransform.1: transform
		136	...
		137
		138	For example, the following will transform selections of the form
		139	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		140	$word>:
		141
		142	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		143
		144	And this example matches the same,but replaces it with vi-commands you can
		145	paste directly into your (vi :) editor:
		146
		147	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
		148
		149	Of course, this can be modified to suit your needs and your editor :)
		150
		151	To expand the example above to typical perl error messages ("XXX at
		152	FILENAME line YYY."), you need a slightly more elaborate solution:
		153
		154	URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
		155	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
		156
		157	The first line tells the selection code to treat the unchanging part of
		158	every error message as a selection pattern, and the second line transforms
		159	the message into vi commands to load the file.

		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

		246
		247	Dynamically enable the given hooks (named without the C<on_> prefix) for
		248	this extension, replacing any previous hook. This is useful when you want
		249	to overwrite time-critical hooks only temporarily.
