What a wonderful question. I am not certain what you mean by reverse, though. Please explain what your last laptop did, and maybe we can discuss options that are availabe to you.
Oh, ok. I have no experince with hacking User Interfaces at the machine level, so I am not familiar with altering the root funcitons of an interface. Now, you would probably be able to find some middle-ware someplace that will "control" your sound hardware with a few key strokes, but I am certain you will be paying for it in performance and "sniffing" (malware) issues. And it will still take a magical keystroke of a couple keys to make it happen, just as with the FN+F11 does now. So really is it worth it?
