		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.

		69	text into various other formats/action.

		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,

		117
		118	A perl text string, with an emphasis on I<text>. It can store all unicode

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

		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

		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

		923
		924	=item $modifiermask = $term->ModMetaMask
		925
		926	=item $modifiermask = $term->ModNumLockMask
		927
		928	Return the modifier masks corresponding to the "ISO Level 3 Shift" (often
		929	AltGr), the meta key (often Alt) and the num lock key, if applicable.
		930
		931	=item $view_start = $term->view_start ([$newvalue])
		932
		933	Returns the negative row number of the topmost line. Minimum value is
		934	C<0>, which displays the normal terminal contents. Larger values scroll
		935	this many lines into the scrollback buffer.
		936
		937	=item $term->want_refresh
		938
		939	Requests a screen refresh. At the next opportunity, rxvt-unicode will
		940	compare the on-screen display with its stored representation. If they
		941	differ, it redraws the differences.
		942
		943	Used after changing terminal contents to display them.
		944
		945	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		946
		947	Returns the text of the entire row with number C<$row_number>. Row C<0>
		948	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		949	terminal line. The scrollback buffer starts at line C<-1> and extends to
		950	line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line
		951	is requested.
		952
		953	If C<$new_text> is specified, it will replace characters in the current
		954	line, starting at column C<$start_col> (default C<0>), which is useful
		955	to replace only parts of a line. The font index in the rendition will
		956	automatically be updated.
		957
		958	C<$text> is in a special encoding: tabs and wide characters that use more
		959	than one cell when displayed are padded with urxvt::NOCHAR characters
		960	(C<chr 65535>). Characters with combining characters and other characters
		961	that do not fit into the normal tetx encoding will be replaced with
		962	characters in the private use area.
		963
		964	You have to obey this encoding when changing text. The advantage is
		965	that C<substr> and similar functions work on screen cells and not on
		966	characters.
		967
		968	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		969	can be used to convert normal strings into this encoding and vice versa.
		970
		971	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		972
		973	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		974	bitsets. Rendition bitsets contain information about colour, font, font
		975	styles and similar information. See also C<< $term->ROW_t >>.
		976
		977	When setting rendition, the font mask will be ignored.
		978
		979	See the section on RENDITION, above.
		980
		981	=item $length = $term->ROW_l ($row_number[, $new_length])
		982
		983	Returns the number of screen cells that are in use ("the line
		984	length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the
		985	line is joined with the following one.
		986
		987	=item $bool = $term->is_longer ($row_number)
		988
		989	Returns true if the row is part of a multiple-row logical "line" (i.e.
		990	joined with the following row), which means all characters are in use
		991	and it is continued on the next row (and possibly a continuation of the
		992	previous row(s)).
		993
		994	=item $line = $term->line ($row_number)
		995
		996	Create and return a new C<urxvt::line> object that stores information
		997	about the logical line that row C<$row_number> is part of. It supports the
		998	following methods:
		999
		1000	=over 4
		1001
		1002	=item $text = $line->t ([$new_text])
		1003
		1004	Returns or replaces the full text of the line, similar to C<ROW_t>
		1005
		1006	=item $rend = $line->r ([$new_rend])
		1007
		1008	Returns or replaces the full rendition array of the line, similar to C<ROW_r>
		1009
		1010	=item $length = $line->l
		1011
		1012	Returns the length of the line in cells, similar to C<ROW_l>.
		1013
		1014	=item $rownum = $line->beg
		1015
		1016	=item $rownum = $line->end
		1017
		1018	Return the row number of the first/last row of the line, respectively.
		1019
		1020	=item $offset = $line->offset_of ($row, $col)
		1021
		1022	Returns the character offset of the given row\|col pair within the logical
		1023	line.
		1024
		1025	=item ($row, $col) = $line->coord_of ($offset)
		1026
