13 Also, on most hardware, keeping a key pressed for more than a few dozens of
14 milliseconds produce a repeat key event. That's somewhat similar to what
22 produces one event for a key press and another one for key release. On
23 infrared-based remote controllers, there's no key release event. Instead,
24 an extra code is produced to indicate key repeats.
