		33	This section describes the extensiosn delivered with this version. You can
		34	find them in F<@@RXVT_LIBDIR@@/urxvt/perl/>.

		41
		42	=item selection (enabled by default)
		43
		44	Intelligent selection. This extension tries to be more intelligent when
		45	the user extends selections (double-click). Right now, it tries to select
		46	urls and complete shell-quoted arguments, which is very convenient, too,
		47	if your F<ls> supports C<--quoting-style=shell>.
		48
		49	It also offers the following bindable event:

		64	runtime.

		66	=item selection-popup (enabled by default)
		67
		68	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
		69	text into various other formats/action.

		72
		73	Displays a digital clock using the built-in overlay.

		77	Uses per-line display filtering (C<on_line_update>) to underline urls.
		78
		79	=item block-graphics-to-ascii
		80
		81	A not very useful example of filtering all text output to the terminal,
		82	by replacing all line-drawing characters (U+2500 .. U+259F) by a
		83	similar-looking ascii character.

		115
		116	=item $string
		117
		118	A perl text string, with an emphasis on I<text>. It can store all unicode
		119	characters and is to be distinguished with text encoded in a specific
		120	encoding (often locale-specific) and binary data.

		213	operating system command) is processed. Cursor position and other state
		214	information is up-to-date when this happens. For interoperability, the

		219	Be careful not ever to trust (in a security sense) the data you receive,

		223	=item on_add_lines $term, $string
		224
		225	Called whenever text is about to be output, with the text as argument. You
		226	can filter/change and output the text yourself by returning a true value
		227	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		228	might be very slow, however, as your hook is called for B<all> text being
		229	output.
		230
		231	=item on_line_update $term, $row
		232
		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 lines
		235	that are being shown will be filtered, and, due to performance reasons,
		236	not always immediately.
		237
		238	The row number is always the topmost row of the line if the line spans
		239	multiple rows.
		240
		241	Please note that, if you change the line, then the hook might get called
		242	later with the already-modified line (e.g. if unrelated parts change), so

		919
		920	Return various integers describing terminal characteristics.
		921
		922	=item $lc_ctype = $term->locale
		923
		924	Returns the LC_CTYPE category string used by this rxvt-unicode.
		925
		926	=item $x_display = $term->display_id
		927
		928	Return the DISPLAY used by rxvt-unicode.
		929

		931
		932	=item $modifiermask = $term->ModMetaMask
		933
		934	=item $modifiermask = $term->ModNumLockMask
		935
		936	Return the modifier masks corresponding to the "ISO Level 3 Shift" (often
		937	AltGr), the meta key (often Alt) and the num lock key, if applicable.
		938
		939	=item $view_start = $term->view_start ([$newvalue])
		940
		941	Returns the negative row number of the topmost line. Minimum value is
		942	C<0>, which displays the normal terminal contents. Larger values scroll
		943	this many lines into the scrollback buffer.
		944
		945	=item $term->want_refresh
		946
		947	Requests a screen refresh. At the next opportunity, rxvt-unicode will
		948	compare the on-screen display with its stored representation. If they
		949	differ, it redraws the differences.
		950
		951	Used after changing terminal contents to display them.
		952
		953	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		954
		955	Returns the text of the entire row with number C<$row_number>. Row C<0>
		956	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		957	terminal line. The scrollback buffer starts at line C<-1> and extends to
		958	line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line
		959	is requested.
		960
		961	If C<$new_text> is specified, it will replace characters in the current
		962	line, starting at column C<$start_col> (default C<0>), which is useful
		963	to replace only parts of a line. The font index in the rendition will
		964	automatically be updated.
		965
		966	C<$text> is in a special encoding: tabs and wide characters that use more
		967	than one cell when displayed are padded with urxvt::NOCHAR characters
		968	(C<chr 65535>). Characters with combining characters and other characters
		969	that do not fit into the normal tetx encoding will be replaced with
		970	characters in the private use area.
		971
		972	You have to obey this encoding when changing text. The advantage is
		973	that C<substr> and similar functions work on screen cells and not on
		974	characters.
		975
		976	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		977	can be used to convert normal strings into this encoding and vice versa.
		978
		979	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		980
		981	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		982	bitsets. Rendition bitsets contain information about colour, font, font
		983	styles and similar information. See also C<< $term->ROW_t >>.
		984
		985	When setting rendition, the font mask will be ignored.
		986
		987	See the section on RENDITION, above.
		988
		989	=item $length = $term->ROW_l ($row_number[, $new_length])
		990
		991	Returns the number of screen cells that are in use ("the line
		992	length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the
		993	line is joined with the following one.
		994
		995	=item $bool = $term->is_longer ($row_number)
		996
		997	Returns true if the row is part of a multiple-row logical "line" (i.e.
		998	joined with the following row), which means all characters are in use
		999	and it is continued on the next row (and possibly a continuation of the
		1000	previous row(s)).
		1001
		1002	=item $line = $term->line ($row_number)
		1003
		1004	Create and return a new C<urxvt::line> object that stores information
		1005	about the logical line that row C<$row_number> is part of. It supports the
		1006	following methods:
		1007
		1008	=over 4
		1009
		1010	=item $text = $line->t ([$new_text])
		1011
		1012	Returns or replaces the full text of the line, similar to C<ROW_t>
		1013
		1014	=item $rend = $line->r ([$new_rend])
		1015
		1016	Returns or replaces the full rendition array of the line, similar to C<ROW_r>
		1017
		1018	=item $length = $line->l
		1019
		1020	Returns the length of the line in cells, similar to C<ROW_l>.
		1021
		1022	=item $rownum = $line->beg
		1023
		1024	=item $rownum = $line->end
		1025
		1026	Return the row number of the first/last row of the line, respectively.
		1027
		1028	=item $offset = $line->offset_of ($row, $col)
		1029
		1030	Returns the character offset of the given row\|col pair within the logical
		1031	line.
		1032
		1033	=item ($row, $col) = $line->coord_of ($offset)
		1034
