|
|
161 | cursor-left or cursor-right keypresses as required (the this only works |

|
|
218 | This transforms the terminal into a tabbar with additional terminals, that |
|
|
219 | is, it implements what is commonly refered to as "tabbed terminal". The topmost line |
|
|
220 | displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
|
|
221 | button per tab. |
|
|
222 | |
|
|
223 | Clicking a button will activate that tab. Pressing B<Shift-Left> and |
|
|
224 | B<Shift-Right> will switch to the tab left or right of the current one, |
|
|
225 | while B<Shift-Down> creates a new tab. |
|
|
226 | |
|
|
227 | The tabbar itself can be configured similarly to a normal terminal, but |
|
|
228 | with a resource class of C<URxvt.tabbed>. In addition, it supports the |
