48		53
		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	Another example: Programs I use often output "absolute path: " at the
		73	beginning of a line when they process multiple files. The following
		74	pattern matches the filename (note, there is a single space at the very
		75	end):
		76
		77	URxvt.selection.pattern-0: ^(/[^:]+):\
		78
		79	You can look at the source of the selection extension to see more
		80	interesting uses, such as parsing a line from beginning to end.

		104
		105	Other extensions can extend this popup menu by pushing a code reference
		106	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
		107	popup is displayed.
		108
		109	It's sole argument is the popup menu, which can be modified. The selection
		110	is in C<$_>, which can be used to decide wether to add something or not.
		111	It should either return nothing or a string and a code reference. The
		112	string will be used as button text and the code reference will be called
		113	when the button gets activated and should transform C<$_>.
		114
		115	The following will add an entry C<a to b> that transforms all C<a>s in
		116	the selection to C<b>s, but only if the selection currently contains any
		117	C<a>s:
		118
		119	push @{ $self->{term}{selection_popup_hook} }, sub {

		137	selection.

83	=item digital-clock	139	=item readline (enabled by default)

85	Displays a digital clock using the built-in overlay.	141	A support package that tries to make editing with readline easier. At the
		142	moment, it reacts to clicking with the left mouse button by trying to
		143	move the text cursor to this position. It does so by generating as many
		144	cursor-left or cursor-right keypresses as required (the this only works
		145	for programs that correctly support wide characters).
		146
		147	To avoid too many false positives, this is only done when:
		148
		149	=over 4
		150
		151	=item - the tty is in ICANON state.
		152
		153	=item - the text cursor is visible.
		154
		155	=item - the primary screen is currently being displayed.
		156
		157	=item - the mouse is on the same (multi-row-) line as the text cursor.
		158
		159	=back
		160
		161	The normal selection mechanism isn't disabled, so quick successive clicks
		162	might interfere with selection creation in harmless ways.
		163
		164	=item selection-autotransform
		165
		166	This selection allows you to do automatic transforms on a selection
		167	whenever a selection is made.
		168
		169	It works by specifying perl snippets (most useful is a single C<s///>
		170	operator) that modify C<$_> as resources:
		171
		172	URxvt.selection-autotransform.0: transform
		173	URxvt.selection-autotransform.1: transform
		174	...
		175
		176	For example, the following will transform selections of the form
		177	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		178	$word>:
		179
		180	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		181
		182	And this example matches the same,but replaces it with vi-commands you can
		183	paste directly into your (vi :) editor:
		184
		185	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		186
		187	Of course, this can be modified to suit your needs and your editor :)
		188
		189	To expand the example above to typical perl error messages ("XXX at
		190	FILENAME line YYY."), you need a slightly more elaborate solution:
		191
		192	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		193	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		194
		195	The first line tells the selection code to treat the unchanging part of
		196	every error message as a selection pattern, and the second line transforms
		197	the message into vi commands to load the file.
		198
		199	=item tabbed
		200
		201	This transforms the terminal into a tabbar with additional terminals, that
		202	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		203	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		204	button per tab.
		205
		206	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		207	B<Shift-Right> will switch to the tab left or right of the current one,
		208	while B<Shift-Down> creates a new tab.
		209
		210	The tabbar itself can be configured similarly to a normal terminal, but
		211	with a resource class of C<URxvt.tabbed>. In addition, it supports the
		212	following four resources (shown with defaults):
		213
		214	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
		215	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
		216	URxvt.tabbed.tab-fg: <colour-index, default 0>
		217	URxvt.tabbed.tab-bg: <colour-index, default 1>
		218
		219	See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
		220	indices.

		227	the URL as first argument.
		228
		229	=item xim-onthespot
		230
		231	This (experimental) perl extension implements OnTheSpot editing. It does
		232	not work perfectly, and some input methods don't seem to work well with
		233	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		234	kinput2.
		235
		236	You enable it by specifying this extension and a preedit style of
		237	C<OnTheSpot>, i.e.:
		238
		239	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		240
		241	=item automove-background
		242
		243	This is basically a one-line extension that dynamically changes the background pixmap offset
		244	to the window position, in effect creating the same effect as pseudo transparency with
		245	a custom pixmap. No scaling is supported in this mode. Exmaple:
		246

		254
		255	=item digital-clock
		256
		257	Displays a digital clock using the built-in overlay.
		258
		259	=item remote-clipboard
		260
		261	Somewhat of a misnomer, this extension adds two menu entries to the
		262	selection popup that allows one ti run external commands to store the
		263	selection somewhere and fetch it again.
		264
		265	We use it to implement a "distributed selection mechanism", which just
		266	means that one command uploads the file to a remote server, and another
		267	reads it.
		268
		269	The commands can be set using the C<URxvt.remote-selection.store> and
		270	C<URxvt.remote-selection.fetch> resources. The first should read the
		271	selection to store from STDIN (always in UTF-8), the second should provide
		272	the selection data on STDOUT (also in UTF-8).
		273
		274	The defaults (which are likely useless to you) use rsh and cat:
		275
		276	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		277	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		278
		279	=item selection-pastebin
		280
		281	This is a little rarely useful extension that Uploads the selection as
		282	textfile to a remote site (or does other things). (The implementation is
		283	not currently secure for use in a multiuser environment as it writes to
		284	F</tmp> directly.).
		285
		286	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		287	i.e.
		288
		289	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		290
		291	Pressing this combination runs a command with C<%> replaced by the name of
		292	the textfile. This command can be set via a resource:
		293
		294	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		295
		296	And the default is likely not useful to anybody but the few people around
		297	here :)
		298
		299	The name of the textfile is the hex encoded md5 sum of the selection, so
		300	the same content should lead to the same filename.
		301
		302	After a successful upload the selection will be replaced by the text given
		303	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		304	for the filename):
		305
		306	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
