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