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