Comment 5 for bug 1343112

The existing controls (_set_zero, _set_one, _toggle, _set_minus_one, etc.) cover 90% of the use cases I think so this is pretty low priority -- nobody is working on it at the moment (that I know of)?

Keyboard control will hopefully get a revamp in the next year so that you can do assignments via GUI and so on. Maybe someone will implement it then?
