139 | =item readline (enabled by default) |
|
|
140 | |
|
|
141 | A support package that tries to make editing with readline easier. At the |
|
|
142 | moment, it reacts to clicking with the left mouse button by trying to |
|
|
143 | move the text cursor to this position. It does so by generating as many |
|
|
144 | cursor-left or cursor-right keypresses as required (the this only works |
|
|
145 | for programs that correctly support wide characters). |
|
|
146 | |
|
|
147 | To avoid too many false positives, this is only done when: |
