I disagree. This is something that Apple figured out years ago (and subsequently forgot, the company has definitely reached senility at this point, but I digress.) You should definitely not be getting visual feedback if you hit a control button and start typing - at that point the interface should be concentrating on accepting your input not on talking back. WHEN and IF you pause, hesitate for a moment, THEN it's appropriate to think about bringing up a visual hint. Bringing it up every time is NOT helpful it's annoying as all fsck, the result is a very annoying system that effectively is always talking instead of listening. Bad computer!
