Hi João

If the first bang is triggered, wait some time and if within this time
frame the second is triggered as well, then you know the direction. It's
actually mostly about timing and to make sure to clear the state after a
certain time, if not both bangs are triggered within the time frame.

Check the attached (ugly; done with touchpad) patch.
