-This hook is one of the four "official" hooks defined in ti83plus.inc.  However, it appears that someone at TI made a mistake in adding its address, because it does not in fact have anything to do with "raw" keys.  It has been suggested that this was intended to be called the "GetKey" hook.  To avoid possible confusion with [[83Plus:Hooks:9B88h|another hook]], the name "Raw Key" should be used nevertheless.
