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 the following bindable keyboard command:

84	Displays a digital clock using the built-in overlay.	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	$word>:
		124
		125	URxvt.selection-autotransform.0: s/^(\\S+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		126
		127	And this example matches the same,but replaces it with vi-commands you can
		128	paste directly into your (vi :) editor:
		129
		130	URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/

361
362	Creates a new terminal, very similar as if you had started it with
363	C<system $binfile, arg...>. Croaks (and probably outputs an error message)
364	if the new instance couldn't be created. Returns C<undef> if the new
365	instance didn't initialise perl, and the terminal object otherwise. The
366	C<init> and C<start> hooks will be called during the call.
367
368	=item urxvt::fatal $errormessage
369
370	Fatally aborts execution with the given error message. Avoid at all
371	costs! The only time this is acceptable is when the terminal process
372	starts up.
373
374	=item urxvt::warn $string
375
376	Calls C<rxvt_warn> with the given string which should not include a
377	newline. The module also overwrites the C<warn> builtin with a function
378	that calls this function.
379
380	Using this function has the advantage that its output ends up in the
381	correct place, e.g. on stderr of the connecting urxvtc client.

406	similar information for each screen cell.
407
408	The following "macros" deal with changes in rendition sets. You should
409	never just create a bitset, you should always modify an existing one,
410	as they contain important information required for correct operation of
411	rxvt-unicode.
