167 | A support package that tries to make editing with readline easier. At |
|
|
168 | the moment, it reacts to clicking shift-left mouse button by trying to |
|
|
169 | move the text cursor to this position. It does so by generating as many |
|
|
170 | cursor-left or cursor-right keypresses as required (this only works |
|
|
171 | for programs that correctly support wide characters). |
|
|

168 | |
226 | |
|
|
227 | This transforms the terminal into a tabbar with additional terminals, that |
|
|
228 | is, it implements what is commonly referred to as "tabbed terminal". The topmost line |
|
|
229 | displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
|
|
230 | button per tab. |
|
|
231 | |
|
|
232 | Clicking a button will activate that tab. Pressing B<Shift-Left> and |
|
|
233 | B<Shift-Right> will switch to the tab left or right of the current one, |
|
|
234 | while B<Shift-Down> creates a new tab. |
|
|
235 | |
|
|
236 | The tabbar itself can be configured similarly to a normal terminal, but |
|
|
237 | with a resource class of C<URxvt.tabbed>. In addition, it supports the |

238 | following four resources (shown with defaults): |

|
|
290 | |
|
|
291 | A very primitive quake-console-like extension. It was inspired by a |
|
|
292 | description of how the programs C<kuake> and C<yakuake> work: Whenever the |
|
|
293 | user presses a global accelerator key (by default C<F10>), the terminal |
|
|
294 | will show or hide itself. Another press of the accelerator key will hide |
|
|
295 | or show it again. |
|

296 | |
|
|
297 | Initially, the window will not be shown when using this extension. |

|
299 | This is useful if you need a single terminal that is not using any desktop |
|
|
300 | space most of the time but is quickly available at the press of a key. |
|
|
301 | |
|
|
302 | The accelerator key is grabbed regardless of any modifiers, so this |
|
|
303 | extension will actually grab a physical key just for this function. |
