tabbed - tabbed interface to urxvt

=head1 DESCRIPTION

This transforms the terminal into a tabbar with additional terminals, that
is, it implements what is commonly referred to as "tabbed terminal". The topmost line
displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
button per tab.

Clicking a button will activate that tab. Pressing B<Shift-Left> and
B<Shift-Right> will switch to the tab left or right of the current one,
while B<Shift-Down> creates a new tab. Pressing B<Ctrl-Left> and
B<Ctrl-Right> will renumber the current tab by moving it to the left or
to the right.

The tabbar itself can be configured similarly to a normal terminal, but
with a resource class of C<URxvt.tabbed>. In addition, it supports the
following four resources (shown with defaults):

   URxvt.tabbed.tabbar-fg: <colour-index, default 3>
   URxvt.tabbed.tabbar-bg: <colour-index, default 0>
   URxvt.tabbed.tab-fg:    <colour-index, default 0>
   URxvt.tabbed.tab-bg:    <colour-index, default 1>

See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
indices.
