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:

		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.
80		108
81	Displays a digital clock using the built-in overlay.	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<$_> as resources:
		116
		117	URxvt.selection-autotransform.0: transform
		118	URxvt.selection-autotransform.1: transform
		119	...
		120
		121	For example, the following will transform selections of the form
		122	C<word:number> into C<vi +$number $word>:
		123
		124	URxvt.selection-autotransform.0: s/^(S+):(d+):?$/vi +$2 $1\\x0d/
		125
		126	And this example matches the same,but replaces it with vi-commands you can
		127	paste directory into your (vi :) editor:
		128
		129	URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\\x1b:e $1\\x0d:$2\\x0d/

358
359	Creates a new terminal, very similar as if you had started it with
360	C<system $binfile, arg...>. Croaks (and probably outputs an error message)
361	if the new instance couldn't be created. Returns C<undef> if the new
362	instance didn't initialise perl, and the terminal object otherwise. The
363	C<init> and C<start> hooks will be called during the call.

365	=item urxvt::fatal $errormessage
366
367	Fatally aborts execution with the given error message. Avoid at all
368	costs! The only time this is acceptable is when the terminal process
369	starts up.
370
371	=item urxvt::warn $string
372
373	Calls C<rxvt_warn> with the given string which should not include a
374	newline. The module also overwrites the C<warn> builtin with a function
375	that calls this function.
376
377	Using this function has the advantage that its output ends up in the
378	correct place, e.g. on stderr of the connecting urxvtc client.

405	The following "macros" deal with changes in rendition sets. You should
