		139	=item readline (enabled by default)
		140
		141	A support package that tries to make editing with readline easier. At the
		142	moment, it reacts to clicking with the left mouse button by trying to
		143	move the text cursor to this position. It does so by generating as many
		144	cursor-left or cursor-right keypresses as required (the this only works
		145	for programs that correctly support wide characters).
		146
		147	To avoid too many false positives, this is only done when:
		148
		149	=over 4

		151	=item - the tty is in ICANON state.

		158

		162	might interfere with selection creation in harmless ways.

		200
		201	This transforms the terminal into a tabbar with additional terminals, that
		202	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		203	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		204	button per tab.
		205
		206	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		207	B<Shift-Right> will switch to the tab left or right of the current one,
		208	while B<Shift-Down> creates a new tab.
		209
		210	The tabbar itself can be configured similarly to a normal terminal, but
		211	with a resource class of C<URxvt.tabbed>. In addition, it supports the
		212	following four resources (shown with defaults):
		213
		214	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
		215	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
