twofing currently recognizes the following two-fingered gestures: Two-fingered tap, two-fingered scroll, two-fingered zoom, two-fingered rotate. It blocks input so these gestures don't reach the underlying application as normal mouse events. It creates mouse and key events and sends them to the application instead. To be able to do this, the daemon needs different profiles for different applications. Here is what should work at the moment:
- Eye of Gnome (Ubuntu's default picture viewer): Zoom, scroll, rotate, right click
- Evince (Ubuntu's default document (PDF) viewer): Zoom, scroll, rotate, right click
- F-Spot: Zoom, scroll, right click
- Almost every other application: Scroll, right click, for many (like Firefox, Nautilus, LibreOffice/OpenOffice) also zoom
Unfortunately, applications which use extended input
capabilities like Gimp, Xournal or MyPaint don't work correctly with the
daemon if extended input is enabled in these applications.
