		566
		567	=item $nsaved = $term->nsaved
		568
		569	Returns the number of lines in the scrollback buffer.
		570
		571	=item $view_start = $term->view_start ([$newvalue])
		572
		573	Returns the negative row number of the topmost line. Minimum value is
		574	C<0>, which displays the normal terminal contents. Larger values scroll
		575	this many lines into the scrollback buffer.
		576
		577	=item $term->want_refresh
		578
		579	Requests a screen refresh. At the next opportunity, rxvt-unicode will
		580	compare the on-screen display with its stored representation. If they
		581	differ, it redraws the differences.
		582
		583	Used after changing terminal contents to display them.
		584
		585	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		586
		587	Returns the text of the entire row with number C<$row_number>. Row C<0>
		588	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		589	terminal line. The scrollback buffer starts at line C<-1> and extends to
		590	line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line
		591	is requested.
		592
		593	If C<$new_text> is specified, it will replace characters in the current
		594	line, starting at column C<$start_col> (default C<0>), which is useful
		595	to replace only parts of a line. The font index in the rendition will
		596	automatically be updated.
		597
		598	C<$text> is in a special encoding: tabs and wide characters that use more
		599	than one cell when displayed are padded with urxvt::NOCHAR characters
		600	(C<chr 65535>). Characters with combining characters and other characters
		601	that do not fit into the normal tetx encoding will be replaced with
		602	characters in the private use area.
		603
		604	You have to obey this encoding when changing text. The advantage is
		605	that C<substr> and similar functions work on screen cells and not on
		606	characters.
		607
		608	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		609	can be used to convert normal strings into this encoding and vice versa.
		610
		611	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		612
		613	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		614	bitsets. Rendition bitsets contain information about colour, font, font
		615	styles and similar information. See also C<< $term->ROW_t >>.
		616
		617	When setting rendition, the font mask will be ignored.
		618
		619	See the section on RENDITION, above.
		620
		621	=item $length = $term->ROW_l ($row_number[, $new_length])
		622
		623	Returns the number of screen cells that are in use ("the line
		624	length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the
		625	line is joined with the following one.
		626
		627	=item $bool = $term->is_longer ($row_number)
		628
		629	Returns true if the row is part of a multiple-row logical "line" (i.e.
		630	joined with the following row), which means all characters are in use
		631	and it is continued on the next row (and possibly a continuation of the
		632	previous row(s)).
		633
		634	=item $line = $term->line ($row_number)
		635
		636	Create and return a new C<urxvt::line> object that stores information
		637	about the logical line that row C<$row_number> is part of. It supports the
		638	following methods:
		639
		640	=over 4
		641
		642	=item $text = $line->t
		643
		644	Returns the full text of the line, similar to C<ROW_t>
		645
		646	=item $rend = $line->r
		647
		648	Returns the full rendition array of the line, similar to C<ROW_r>
		649
		650	=item $length = $line->l
		651
		652	Returns the length of the line in cells, similar to C<ROW_l>.
		653

		655
		656	=item $rownum = $line->end
