		435	=item $nrow = $term->nrow
		436
		437	=item $ncol = $term->ncol
		438
		439	Return the number of rows/columns of the terminal window (i.e. as
		440	specified by C<-geometry>, excluding any scrollback).
		441
		442	=item $nsaved = $term->nsaved
		443
		444	Returns the number of lines in the scrollback buffer.
		445
		446	=item $view_start = $term->view_start ([$newvalue])
		447
		448	Returns the negative row number of the topmost line. Minimum value is
		449	C<0>, which displays the normal terminal contents. Larger values scroll
		450	this many lines into the scrollback buffer.
		451
		452	=item $term->want_refresh
		453
		454	Requests a screen refresh. At the next opportunity, rxvt-unicode will
		455	compare the on-screen display with its stored representation. If they
		456	differ, it redraws the differences.
		457
		458	Used after changing terminal contents to display them.
		459
		460	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		461
		462	Returns the text of the entire row with number C<$row_number>. Row C<0>
		463	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		464	terminal line. The scrollback buffer starts at line C<-1> and extends to
		465	line C<< -$term->nsaved >>.
		466
		467	If C<$new_text> is specified, it will replace characters in the current
		468	line, starting at column C<$start_col> (default C<0>), which is useful
		469	to replace only parts of a line. The font iindex in the rendition will
		470	automatically be updated.
		471
		472	C<$text> is in a special encoding: tabs and wide characters that use more
		473	than one cell when displayed are padded with urxvt::NOCHAR characters
		474	(C<chr 65535>). Characters with combining characters and other characters
		475	that do not fit into the normal tetx encoding will be replaced with
		476	characters in the private use area.
		477
		478	You have to obey this encoding when changing text. The advantage is
		479	that C<substr> and similar functions work on screen cells and not on
		480	characters.
		481
		482	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		483	can be used to convert normal strings into this encoding and vice versa.
		484
		485	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		486
		487	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		488	bitsets. Rendition bitsets contain information about colour, font, font
		489	styles and similar information. See also C<< $term->ROW_t >>.
		490
		491	When setting rendition, the font mask will be ignored.
		492
		493	See the section on RENDITION, below.
		494
		495	=item $length = $term->ROW_l ($row_number[, $new_length])
		496
		497	Returns the number of screen cells that are in use ("the line length"). If
		498	it is C<-1>, then the line is part of a multiple-row logical "line", which
		499	means all characters are in use and it is continued on the next row.
		500
		501	=item $text = $term->special_encode $string
		502
		503	Converts a perl string into the special encoding used by rxvt-unicode,
		504	where one character corresponds to one screen cell. See
		505	C<< $term->ROW_t >> for details.
		506
		507	=item $string = $term->special_decode $text
		508
		509	Converts rxvt-unicodes text reprsentation into a perl string. See
		510	C<< $term->ROW_t >> for details.
		511
390	=back	512	=back
		513
		514	=head2 RENDITION
		515
		516	Rendition bitsets contain information about colour, font, font styles and
		517	similar information for each screen cell.
		518
		519	The following "macros" deal with changes in rendition sets. You should
		520	never just create a bitset, you should always modify an existing one,
		521	as they contain important information required for correct operation of
		522	rxvt-unicode.
		523
		524	=over 4
		525
		526	=item $rend = urxvt::DEFAULT_RSTYLE
		527
		528	Returns the default rendition, as used when the terminal is starting up or
		529	being reset. Useful as a base
