		98	Argument names also often indicate the type of a parameter. Here are
		99	some hints on what they mean:
		100
		101	$text
		102	Rxvt-unicodes special way of encoding text, where one "unicode"
		103	character always represents one screen cell. See row_t for a
		104	discussion of this format.
		105
		106	$string
		107	A perl text string, with an emphasis on text. It can store all
		108	unicode characters and is to be distinguished with text encoded in a
		109	specific encoding (often locale-specific) and binary data.
		110
		111	$octets
		112	Either binary data or - more common - a text string encoded in a
		113	locale-specific way.
		114
		115	Extension Objects
		116	Very perl extension is a perl class. A separate perl object is created
		117	for each terminal and each extension and passed as the first parameter
		118	to hooks. So extensions can use their $self object without having to
		119	think about other extensions, with the exception of methods and members
		120	that begin with an underscore character "_": these are reserved for
		121	internal use.
		122
		123	Although it isn't a "urxvt::term" object, you can call all methods of
		124	the "urxvt::term" class on this object.
		125
		126	It has the following methods and data members:
		127
		128	$urxvt_term = $self->{term}
		129	Returns the "urxvt::term" object associated with this instance of
		130	the extension. This member must not be changed in any way.
		131
		132	$self->enable ($hook_name => $cb, [$hook_name => $cb..])
		133	Dynamically enable the given hooks (named without the "on_" prefix)
		134	for this extension, replacing any previous hook. This is useful when
		135	you want to overwrite time-critical hooks only temporarily.
		136
		137	$self->disable ($hook_name[, $hook_name..])
		138	Dynamically disable the given hooks.

127	Called whenever the program(s) running in the urxvt window send	210	Called whenever the ESC ] 777 ; string ST command sequence (OSC =
128	output.	211	operating system command) is processed. Cursor position and other
		212	state information is up-to-date when this happens. For
		213	interoperability, the string should start with the extension name
		214	and a colon, to distinguish it from commands for other extensions,
		215	and this might be enforced in the future.
		216
		217	Be careful not ever to trust (in a security sense) the data you
		218	receive, as its source can not easily be controleld (e-mail content,
		219	messages from other users on the same system etc.).
		220
		221	on_add_lines $term, $string
		222	Called whenever text is about to be output, with the text as
		223	argument. You can filter/change and output the text yourself by
		224	returning a true value and calling "$term->scr_add_lines" yourself.
		225	Please note that this might be very slow, however, as your hook is
		226	called for all text being output.
		227
		228	on_tt_write $term, $octets
		229	Called whenever some data is written to the tty/pty and can be used
		230	to suppress or filter tty input.
		231
		232	on_line_update $term, $row
		233	Called whenever a line was updated or changed. Can be used to filter
		234	screen output (e.g. underline urls or other useless stuff). Only
		235	lines that are being shown will be filtered, and, due to performance
		236	reasons, not always immediately.
		237
		238	The row number is always the topmost row of the line if the line
		239	spans multiple rows.
		240
		241	Please note that, if you change the line, then the hook might get
		242	called later with the already-modified line (e.g. if unrelated parts
		243	change), so you cannot just toggle rendition bits, but only set
		244	them.

		261	Called whenever the window gets the keyboard focus, before
		262	rxvt-unicode does focus in processing.
		263
		264	on_focus_out $term
		265	Called wheneever the window loses keyboard focus, before

		278
		279	The event is a hash with most values as named by Xlib (see the

		341
		342	RENDITION
		343	Rendition bitsets contain information about colour, font, font styles
		344	and similar information for each screen cell.
		345
		346	The following "macros" deal with changes in rendition sets. You should
		347	never just create a bitset, you should always modify an existing one, as
		348	they contain important information required for correct operation of
		349	rxvt-unicode.
		350
		351	$rend = urxvt::DEFAULT_RSTYLE
		352	Returns the default rendition, as used when the terminal is starting
		353	up or being reset. Useful as a base to start when creating
		354	renditions.
		355
		356	$rend = urxvt::OVERLAY_RSTYLE
		357	Return the rendition mask used for overlays by default.
		358
		359	$rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
		360	Return the bit that enabled bold, italic, blink, reverse-video and
		361	underline, respectively. To enable such a style, just logically OR
		362	it into the bitset.
		363
		364	$foreground = urxvt::GET_BASEFG $rend

		371	the specified one.
		372
		373	$value = urxvt::GET_CUSTOM $rend
		374	Return the "custom" value: Every rendition has 5 bits for use by

		376	initially zero.
		377
		378	$rend = urxvt::SET_CUSTOM $rend, $new_value
		379	Change the custom value.
		380
		381	The "urxvt::anyevent" Class
		382	The sole purpose of this class is to deliver an interface to the
		383	"AnyEvent" module - any module using it will work inside urxvt without
		384	further programming. The only exception is that you cannot wait on
		385	condition variables, but non-blocking condvar use is ok. What this means
		386	is that you cannot use blocking APIs, but the non-blocking variant
		387	should work.

		393	(timers, io watchers) are still active.
		394
		395	$isset = $term->option ($optval[, $set])
		396	Returns true if the option specified by $optval is enabled, and
