49	It also offers the following bindable event:	54	A double-click usually selects the word under the cursor, further clicks
		55	will enlarge the selection.
		56
		57	The selection works by trying to match a number of regexes and displaying
		58	them in increasing order of length. You can add your own regexes by
		59	specifying resources of the form:
		60
		61	URxvt.selection.pattern-0: perl-regex
		62	URxvt.selection.pattern-1: perl-regex
		63	...
		64
		65	The index number (0, 1...) must not have any holes, and each regex must
		66	contain at least one pair of capturing parentheses, which will be used for
		67	the match. For example, the followign adds a regex that matches everything
		68	between two vertical bars:
		69
		70	URxvt.selection.pattern-0: \\|([^|]+)\\|
		71
		72	You can look at the source of the selection extension to see more
		73	interesting uses, such as parsing a line from beginning to end.
		74
		75	This extension also offers following bindable keyboard commands:

61	=item digital-clock	87	=item option-popup (enabled by default)
62		88
63	Displays a digital clock using the built-in overlay.	89	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
		90	runtime.
		91
		92	=item selection-popup (enabled by default)
		93
		94	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
		95	text into various other formats/action (such as uri unescaping, perl
		96	evalution, web-browser starting etc.), depending on content.
		97
		98	Other extensions can extend this popup menu by pushing a code reference
		99	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
		100	popup is displayed.
		101
		102	It's sole argument is the popup menu, which can be modified. The selection
		103	is in C<$_>, which can be used to decide wether to add something or not.
		104	It should either return nothing or a string and a code reference. The
		105	string will be used as button text and the code reference will be called
		106	when the button gets activated and should transform C<$_>.
		107
		108	The following will add an entry C<a to b> that transforms all C<a>s in
		109	the selection to C<b>s, but only if the selection currently contains any
		110	C<a>s:
		111
		112	push @{ $self->{term}{selection_popup_hook} }, sub {
		113	/a/ ? ("a to be" => sub { s/a/b/g }
		114	: ()
		115	};
		116
		117	=item searchable-scrollback<hotkey> (enabled by default)
		118
		119	Adds regex search functionality to the scrollback buffer, triggered
		120	by a hotkey (default: C<M-s>). While in search mode, normal terminal
		121	input/output is suspended and a regex is displayed at the bottom of the
		122	screen.
		123
		124	Inputting characters appends them to the regex and continues incremental
		125	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
		126	search upwards/downwards in the scrollback buffer, C<End> jumps to the
		127	bottom. C<Escape> leaves search mode and returns to the point where search
		128	was started, while C<Enter> or C<Return> stay at the current position and
		129	additionally stores the first match in the current line into the primary
		130	selection.
		131
		132	=item selection-autotransform
		133
		134	This selection allows you to do automatic transforms on a selection
		135	whenever a selection is made.
		136
		137	It works by specifying perl snippets (most useful is a single C<s///>
		138	operator) that modify C<$_> as resources:
		139
		140	URxvt.selection-autotransform.0: transform
		141	URxvt.selection-autotransform.1: transform
		142	...
		143
		144	For example, the following will transform selections of the form
		145	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		146	$word>:
		147
		148	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		149
		150	And this example matches the same,but replaces it with vi-commands you can
		151	paste directly into your (vi :) editor:
		152
		153	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		154
		155	Of course, this can be modified to suit your needs and your editor :)
		156
		157	To expand the example above to typical perl error messages ("XXX at
		158	FILENAME line YYY."), you need a slightly more elaborate solution:
		159
		160	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		161	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		162
		163	The first line tells the selection code to treat the unchanging part of
		164	every error message as a selection pattern, and the second line transforms
		165	the message into vi commands to load the file.
64		166
65	=item mark-urls	167	=item mark-urls

67	Uses per-line display filtering (C<on_line_update>) to underline urls.	169	Uses per-line display filtering (C<on_line_update>) to underline urls and
		170	make them clickable. When middle-clicked, the program specified in the
		171	resource C<urlLauncher> (default C<x-www-browser>) will be started with
		172	the URL as first argument.
		173
		174	=item automove-background
		175
		176	This is basically a one-line extension that dynamically changes the background pixmap offset
		177	to the window position, in effect creating the same effect as pseudo transparency with
		178	a custom pixmap. No scaling is supported in this mode. Exmaple:

		198	=item selection-pastebin
		199
		200	This is a little rarely useful extension that Uploads the selection as
		201	textfile to a remote site (or does other things). (The implementation is
		202	not currently secure for use in a multiuser environment as it writes to
		203	F</tmp> directly.).
		204
		205	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		206	i.e.
		207
		208	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		209
		210	Pressing this combination runs a command with C<%> replaced by the name of
		211	the textfile. This command can be set via a resource:
		212
		213	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		214
		215	And the default is likely not useful to anybody but the few people around
		216	here :)
		217
		218	The name of the textfile is the hex encoded md5 sum of the selection, so
		219	the same content should lead to the same filename.
		220
		221	After a successful upload the selection will be replaced by the text given
		222	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		223	for the filename):
		224
		225	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

		267	=head2 Extension Objects
		268
		269	Very perl extension is a perl class. A separate perl object is created
		270	for each terminal and each extension and passed as the first parameter to
		271	hooks. So extensions can use their C<$self> object without having to think
		272	about other extensions, with the exception of methods and members that
		273	begin with an underscore character C<_>: these are reserved for internal
		274	use.
		275
		276	Although it isn't a C<urxvt::term> object, you can call all methods of the
		277	C<urxvt::term> class on this object.
		278
		279	It has the following methods and data members:
		280
		281	=over 4

		289
		290	Dynamically enable the given hooks (named without the C<on_> prefix) for
		291	this extension, replacing any previous hook. This is useful when you want
		292	to overwrite time-critical hooks only temporarily.
