WindowKeyDown vs WindowKeyUp
Most programs respond to WindowKeyDown messages, but not WindowKeyUp messages, because
that is sufficient to react to all keystrokes.
WindowKeyDown messages are created at a rate of about 20 per second if a key is held down for more than about .5 seconds, followed by a single WindowKeyUp when the key is released.
