Maybe some idea, but the keyboard *usually* is in front of the monitor.
One could use a photo diode, and modulate UHF, a van in front of your house
picks it up.
All it would require is that tiny tiny little hole in the keyboard
the photocell peaks through.
Bit far fetched, but technically possible, processing can be done elsewhere.
One channel for keystrokes too.
