an icepick through the keyhole

Cool. But it would be better if it could be set to activate only with certain applications, e.g. your word processor, or better still, only to activate when typing text into a document, as opposed to keyboard shortcuts. The 'Command' key shouldn't make a sound, and any key pressed while the 'Command' key is depressed also shouldn't make a sound. Doesn't 'fit' when doing finder operations.

I know, I know...nit-picking.
