Actually handling KeyPress events wouldn't be that hard, but:

1. Arranging for KeyPress events to be reported is non-trivial. Button
events are always reported to the window under the pointer, but key
events are normally dispatched according to the keyboard focus, and
focus management is non-trivial.

2. How would they be reported?

3. The modal input model implied by R_get_location_* is a hangover
from the days of the Tek-4015 etc. I'm reluctant to put much effort
into extending it, as it's likely to be the first thing to go in the
event of any significant UI update.
