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
		95	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
		96	popup is displayed.
72		97
73	Displays a digital clock using the built-in overlay.	98	It's sole argument is the popup menu, which can be modified. The selection
		99	is in C<$_>, which can be used to decide wether to add something or not.
		100	It should either return nothing or a string and a code reference. The
		101	string will be used as button text and the code reference will be called
		102	when the button gets activated and should transform C<$_>.
		103
		104	The following will add an entry C<a to b> that transforms all C<a>s in
		105	the selection to C<b>s, but only if the selection currently contains any
		106	C<a>s:
		107
		108	push @{ $self->{term}{selection_popup_hook} }, sub {
		109	/a/ ? ("a to be" => sub { s/a/b/g }
		110	: ()
		111	};
		112
		113	=item searchable-scrollback<hotkey> (enabled by default)
		114
		115	Adds regex search functionality to the scrollback buffer, triggered
		116	by a hotkey (default: C<M-s>). While in search mode, normal terminal
		117	input/output is suspended and a regex is displayed at the bottom of the
		118	screen.
		119
		120	Inputting characters appends them to the regex and continues incremental
		121	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
		122	search upwards/downwards in the scrollback buffer, C<End> jumps to the
		123	bottom. C<Escape> leaves search mode and returns to the point where search
		124	was started, while C<Enter> or C<Return> stay at the current position and
		125	additionally stores the first match in the current line into the primary
		126	selection.
		127
		128	=item selection-autotransform
		129
		130	This selection allows you to do automatic transforms on a selection
		131	whenever a selection is made.
		132
		133	It works by specifying perl snippets (most useful is a single C<s///>
		134	operator) that modify C<$_> as resources:
		135
		136	URxvt.selection-autotransform.0: transform
		137	URxvt.selection-autotransform.1: transform
		138	...
		139
		140	For example, the following will transform selections of the form
		141	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		142	$word>:
		143
		144	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		145
		146	And this example matches the same,but replaces it with vi-commands you can
		147	paste directly into your (vi :) editor:
		148
		149	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		150
		151	Of course, this can be modified to suit your needs and your editor :)
		152
		153	To expand the example above to typical perl error messages ("XXX at
		154	FILENAME line YYY."), you need a slightly more elaborate solution:
		155
		156	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		157	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		158
		159	The first line tells the selection code to treat the unchanging part of
		160	every error message as a selection pattern, and the second line transforms
		161	the message into vi commands to load the file.
74		162

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

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

		263	=head2 Extension Objects
		264
		265	Very perl extension is a perl class. A separate perl object is created
		266	for each terminal and each extension and passed as the first parameter to
		267	hooks. So extensions can use their C<$self> object without having to think
		268	about other extensions, with the exception of methods and members that
		269	begin with an underscore character C<_>: these are reserved for internal
		270	use.
		271
		272	Although it isn't a C<urxvt::term> object, you can call all methods of the
		273	C<urxvt::term> class on this object.
		274
		275	It has the following methods and data members:
		276
		277	=over 4

		285
		286	Dynamically enable the given hooks (named without the C<on_> prefix) for

		288	to overwrite time-critical hooks only temporarily.
