34	selection	34	selection (enabled by default)
35	Miscellaneous selection modifications.	35	(More) intelligent selection. This extension tries to be more
		36	intelligent when the user extends selections (double-click and
		37	further clicks). Right now, it tries to select words, urls and
		38	complete shell-quoted arguments, which is very convenient, too, if
		39	your ls supports "--quoting-style=shell".
		40
		41	A double-click usually selects the word under the cursor, further
		42	clicks will enlarge the selection.
		43
		44	The selection works by trying to match a number of regexes and
		45	displaying them in increasing order of length. You can add your own
		46	regexes by specifying resources of the form:
		47
		48	URxvt.selection.pattern-0: perl-regex
		49	URxvt.selection.pattern-1: perl-regex
		50	...
		51
		52	The index number (0, 1...) must not have any holes, and each regex
		53	must contain at least one pair of capturing parentheses, which will
		54	be used for the match. For example, the followign adds a regex that
		55	matches everything between two vertical bars:
		56
		57	URxvt.selection.pattern-0: \\\|([^\|]+)\\\|
		58
		59	You can look at the source of the selection extension to see more
		60	interesting uses, such as parsing a line from beginning to end.
		61
		62	This extension also offers the following bindable keyboard command:

		68
		69	option-popup (enabled by default)
		70	Binds a popup menu to Ctrl-Button2 that lets you toggle (some)
		71	options at runtime.
		72
		73	selection-popup (enabled by default)
		74	Binds a popup menu to Ctrl-Button3 that lets you convert the
		75	selection text into various other formats/action (such as uri
		76	unescaping, perl evalution, web-browser starting etc.), depending on
		77	content.
		78
		79	searchable-scrollback<hotkey> (enabled by default)
		80	Adds regex search functionality to the scrollback buffer, triggered
		81	by a hotkey (default: "M-s"). While in search mode, normal terminal
		82	input/output is suspended and a regex is displayed at the bottom of
		83	the screen.
		84
		85	Inputting characters appends them to the regex and continues
		86	incremental search. "BackSpace" removes a character from the regex,
		87	"Up" and "Down" search upwards/downwards in the scrollback buffer,
		88	"End" jumps to the bottom. "Escape" leaves search mode and returns
		89	to the point where search was started, while "Enter" or "Return"
		90	stay at the current position and additionally stores the first match
		91	in the current line into the primary selection.
		92
		93	selection-autotransform
		94	This selection allows you to do automatic transforms on a selection
		95	whenever a selection is made.
		96
		97	It works by specifying perl snippets (most useful is a single "s///"
		98	operator) that modify $_ as resources:
		99
		100	URxvt.selection-autotransform.0: transform
		101	URxvt.selection-autotransform.1: transform
		102	...
		103
		104	For example, the following will transform selections of the form
		105	"filename:number", often seen in compiler messages, into "vi
		106	+$filename $word":
		107
		108	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		109
		110	And this example matches the same,but replaces it with vi-commands
		111	you can paste directly into your (vi :) editor:
		112
		113	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
		114
		115	Of course, this can be modified to suit your needs and your editor
		116	:)
		117
		118	To expand the example above to typical perl error messages ("XXX at
		119	FILENAME line YYY."), you need a slightly more elaborate solution:
		120
		121	URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
		122	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
		123
		124	The first line tells the selection code to treat the unchanging part
		125	of every error message as a selection pattern, and the second line
		126	transforms the message into vi commands to load the file.
		127
		128	mark-urls
		129	Uses per-line display filtering ("on_line_update") to underline urls
		130	and make them clickable. When middle-clicked, the program specified
		131	in the resource "urlLauncher" (default "x-www-browser") will be
		132	started with the URL as first argument.
		133
		134	block-graphics-to-ascii
		135	A not very useful example of filtering all text output to the
		136	terminal, by replacing all line-drawing characters (U+2500 ..
		137	U+259F) by a similar-looking ascii character.

61		159
		160	Argument names also often indicate the type of a parameter. Here are
		161	some hints on what they mean:
		162
		163	$text
		164	Rxvt-unicodes special way of encoding text, where one "unicode"
		165	character always represents one screen cell. See ROW_t for a
		166	discussion of this format.
		167
		168	$string
		169	A perl text string, with an emphasis on text. It can store all
		170	unicode characters and is to be distinguished with text encoded in a
		171	specific encoding (often locale-specific) and binary data.
		172
		173	$octets
		174	Either binary data or - more common - a text string encoded in a
		175	locale-specific way.
		176
		177	Extension Objects
		178	Very perl extension is a perl class. A separate perl object is created
		179	for each terminal and each extension and passed as the first parameter
		180	to hooks. So extensions can use their $self object without having to
		181	think about other extensions, with the exception of methods and members
		182	that begin with an underscore character "_": these are reserved for
		183	internal use.
		184
		185	Although it isn't a "urxvt::term" object, you can call all methods of
		186	the "urxvt::term" class on this object.
		187
		188	It has the following methods and data members:
		189
		190	$urxvt_term = $self->{term}
		191	Returns the "urxvt::term" object associated with this instance of
		192	the extension. This member must not be changed in any way.
		193
		194	$self->enable ($hook_name => $cb, [$hook_name => $cb..])
		195	Dynamically enable the given hooks (named without the "on_" prefix)
		196	for this extension, replacing any previous hook. This is useful when
		197	you want to overwrite time-critical hooks only temporarily.
		198
		199	$self->disable ($hook_name[, $hook_name..])
		200	Dynamically disable the given hooks.

126	Called whenever the program(s) running in the urxvt window send	275	Called whenever the ESC ] 777 ; string ST command sequence (OSC =
127	output.	276	operating system command) is processed. Cursor position and other
		277	state information is up-to-date when this happens. For
		278	interoperability, the string should start with the extension name
		279	and a colon, to distinguish it from commands for other extensions,
		280	and this might be enforced in the future.
		281
		282	Be careful not ever to trust (in a security sense) the data you
		283	receive, as its source can not easily be controleld (e-mail content,
		284	messages from other users on the same system etc.).
		285
		286	on_add_lines $term, $string
		287	Called whenever text is about to be output, with the text as
		288	argument. You can filter/change and output the text yourself by
		289	returning a true value and calling "$term->scr_add_lines" yourself.
		290	Please note that this might be very slow, however, as your hook is
		291	called for all text being output.
		292
		293	on_tt_write $term, $octets
		294	Called whenever some data is written to the tty/pty and can be used
		295	to suppress or filter tty input.
		296
		297	on_line_update $term, $row
		298	Called whenever a line was updated or changed. Can be used to filter
		299	screen output (e.g. underline urls or other useless stuff). Only
		300	lines that are being shown will be filtered, and, due to performance
		301	reasons, not always immediately.
		302
		303	The row number is always the topmost row of the line if the line
		304	spans multiple rows.
		305
		306	Please note that, if you change the line, then the hook might get
		307	called later with the already-modified line (e.g. if unrelated parts
		308	change), so you cannot just toggle rendition bits, but only set
		309	them.

		325	on_x_event $term, $event
		326	Called on every X event received on the vt window (and possibly
		327	other windows). Should only be used as a last resort. Most event
		328	structure members are not passed.
		329
		330	on_focus_in $term
		331	Called whenever the window gets the keyboard focus, before
		332	rxvt-unicode does focus in processing.
		333

		458	The "urxvt::anyevent" Class
		459	The sole purpose of this class is to deliver an interface to the
