167 | =item readline |
|
|
168 | |
|
|
169 | A support package that tries to make editing with readline easier. At the |
|
|
170 | moment, it reacts to clicking with the left mouse button by trying to |
|
|
171 | move the text cursor to this position. It does so by generating as many |
|
|
172 | cursor-left or cursor-right keypresses as required (the this only works |
|
|
173 | for programs that correctly support wide characters). |
|
|
174 | |
|
|
175 | It only works when clicking into the same line (possibly extended over |
|
|
176 | multiple rows) as the text cursor and on the primary screen, to reduce the |
|
|
177 | risk of misinterpreting. The normal selection isn't disabled, so quick |
|
|
178 | successive clicks might interfere with selection creation in harmless |
|
|
179 | ways. |

181 | =item tabbed |
|

182 | |
|

183 | This transforms the terminal into a tabbar with additional terminals, that |
|
|
184 | is, it implements what is commonly refered to as "tabbed terminal". The topmost line |
|
|
185 | displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
|
|
186 | button per tab. |
|
|
187 | |
|
|
188 | Clicking a button will activate that tab. Pressing B<Shift-Left> and |
|
|
189 | B<Shift-Right> will switch to the tab left or right of the current one, |
|
|
190 | while B<Shift-Down> creates a new tab. |
