*** This depends on the level of software. When you get to a low enough
level ( which Windows surely does ), the keyboard returns "scan codes".
Scan codes tell exactly which keys are pressed. They even tell when a key
is released. Even the scan codes for different keys with the same name are
different. For example, the right-hand & left-hand "shift" keys.
