225 | is, it implements what is commonly referred to as "tabbed terminal". The topmost line |
|
|
226 | displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
|
|
227 | button per tab. |
|
|
228 | |
|
|
229 | Clicking a button will activate that tab. Pressing B<Shift-Left> and |

|
|
232 | |
|
|
233 | The tabbar itself can be configured similarly to a normal terminal, but |
|
|
234 | with a resource class of C<URxvt.tabbed>. In addition, it supports the |

257 | C<matcher.pattern.0> resource, and additional patterns can be specified |

286 | description of how the programs C<kuake> and C<yakuake> work: Whenever the |
|
|
287 | user presses a global accelerator key (by default C<F10>), the terminal |
|
|
288 | will show or hide itself. Another press of the accelerator key will hide |
