		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>.

		210
		211	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		212	operating system command) is processed. Cursor position and other state
		213	information is up-to-date when this happens. For interoperability, the

		215	it from commands for other extensions, and this might be enforced in the

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

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

		920
		921	=item $view_start = $term->view_start ([$newvalue])
		922
		923	Returns the negative row number of the topmost line. Minimum value is
		924	C<0>, which displays the normal terminal contents. Larger values scroll
		925	this many lines into the scrollback buffer.
		926
		927	=item $term->want_refresh
		928
		929	Requests a screen refresh. At the next opportunity, rxvt-unicode will
		930	compare the on-screen display with its stored representation. If they
		931	differ, it redraws the differences.
		932
		933	Used after changing terminal contents to display them.
		934
		935	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		936
		937	Returns the text of the entire row with number C<$row_number>. Row C<0>
		938	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		939	terminal line. The scrollback buffer starts at line C<-1> and extends to
		940	line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line
		941	is requested.
		942
		943	If C<$new_text> is specified, it will replace characters in the current
		944	line, starting at column C<$start_col> (default C<0>), which is useful
		945	to replace only parts of a line. The font index in the rendition will
		946	automatically be updated.
		947
		948	C<$text> is in a special encoding: tabs and wide characters that use more
		949	than one cell when displayed are padded with urxvt::NOCHAR characters
		950	(C<chr 65535>). Characters with combining characters and other characters
		951	that do not fit into the normal tetx encoding will be replaced with
		952	characters in the private use area.
		953
		954	You have to obey this encoding when changing text. The advantage is
		955	that C<substr> and similar functions work on screen cells and not on
		956	characters.
		957
		958	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		959	can be used to convert normal strings into this encoding and vice versa.
		960
		961	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		962
		963	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		964	bitsets. Rendition bitsets contain information about colour, font, font
		965	styles and similar information. See also C<< $term->ROW_t >>.
		966
		967	When setting rendition, the font mask will be ignored.
		968
		969	See the section on RENDITION, above.
		970
		971	=item $length = $term->ROW_l ($row_number[, $new_length])
		972
		973	Returns the number of screen cells that are in use ("the line
		974	length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the
		975	line is joined with the following one.
		976
		977	=item $bool = $term->is_longer ($row_number)
		978
		979	Returns true if the row is part of a multiple-row logical "line" (i.e.
		980	joined with the following row), which means all characters are in use
		981	and it is continued on the next row (and possibly a continuation of the
		982	previous row(s)).
		983
		984	=item $line = $term->line ($row_number)
		985
		986	Create and return a new C<urxvt::line> object that stores information
		987	about the logical line that row C<$row_number> is part of. It supports the
		988	following methods:
		989
		990	=over 4
		991
		992	=item $text = $line->t ([$new_text])
		993
		994	Returns or replaces the full text of the line, similar to C<ROW_t>
		995
		996	=item $rend = $line->r ([$new_rend])
		997
		998	Returns or replaces the full rendition array of the line, similar to C<ROW_r>
		999
		1000	=item $length = $line->l
		1001
		1002	Returns the length of the line in cells, similar to C<ROW_l>.
		1003
		1004	=item $rownum = $line->beg
		1005
		1006	=item $rownum = $line->end
		1007
		1008	Return the row number of the first/last row of the line, respectively.
		1009
		1010	=item $offset = $line->offset_of ($row, $col)
		1011
		1012	Returns the character offset of the given row\|col pair within the logical
		1013	line.
		1014
		1015	=item ($row, $col) = $line->coord_of ($offset)
		1016
		1017	Translates a string offset into terminal coordinates again.
