Just because no existing software takes advantage of it doesn't mean it
won't be useful in the future!

I think the current event library has it about right - the low level
event handler just returns IBMPC sequences.  If you want vt100 sequences
(or indeed X keysyms) then that translation should be done at the next
level up, not in the interrupt handler.  Of course the code could be put
into a library for everyone to use 8-)
