UI possibilities with pressure-sensitive keyboards. When Control-C doesn't work, bang on it harder to kill -9.
@federicomena I remember being a kid and seeing how some people would move game controllers more to the side to make jumps in Super Mario Bros. and shake it around I'm other games too. This was before that would actually do something (motion controls, like on the Wii).
Will we get pressure sensitive keyboards in the future? Perhaps!
At least for the moment, we can implement multiple quick keypresses to mean "really do this, and do it now!"
