Have you considered just storing and using KeyboardInterpreter* here?

I have, there is a comment about that from last review round. I would like to
hold off on flattening the ClientKeyboardDelegate until mod keys and external
keyboards have finished being implemented just incase there is something funky,
and then if ClientKeyboardDelegate is still not doing much work I will axe it.
