10tabbed - tabbed interface to urxvt
11
12=head1 DESCRIPTION
13
14This transforms the terminal into a tabbar with additional terminals, that
15is, it implements what is commonly referred to as "tabbed terminal". The topmost line
16displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
17button per tab.
18
19Clicking a button will activate that tab. Pressing B<Shift-Left> and
20B<Shift-Right> will switch to the tab left or right of the current one,
21while B<Shift-Down> creates a new tab. Pressing B<Ctrl-Left> and
22B<Ctrl-Right> will renumber the current tab by moving it to the left or
23to the right.
24
25The tabbar itself can be configured similarly to a normal terminal, but
26with a resource class of C<URxvt.tabbed>. In addition, it supports the
27following four resources (shown with defaults):
28
29 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
30 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
31 URxvt.tabbed.tab-fg: <colour-index, default 0>
32 URxvt.tabbed.tab-bg: <colour-index, default 1>
33
34See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
35indices.
