There are quite a bit of keyboard code snips...

"// Respond to keyboard input events,
//  intercept cheats. "

And there is also a unit called "unit i_input;" which does a lot of keyboard
translation/input

Something like that might be checking too often or not often enough for keyboard
input - I won't be able to look into it for a while. Jimmy might find something too.
