|
10 | 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. Pressing B<Ctrl-Left> and |
|
|
22 | B<Ctrl-Right> will renumber the current tab by moving it to the left or |
|
|
23 | to the right. |
|
|
24 | |
|
|
25 | The tabbar itself can be configured similarly to a normal terminal, but |
|
|
26 | with a resource class of C<URxvt.tabbed>. In addition, it supports the |
|
|
27 | following 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 | |
|
|
34 | See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid |
|
|
35 | indices. |
