I'd like to know more about this great little app. I'm running a Macbook, so I don't know how it responds on other, more powerful Macs.
As far as I'm aware, the Fn key on any laptop keyboard doesn't generate a scancode (command that corresponds to a function) to make the key transposition easy. Is there a scancode generated by Windows when you press the FN key on a macbook? If so, is there a shift-key-to-enable-capitilisation registry hack going on, using Windows' multimedia keyboard scancodes?
Or is it something more sinister, like hardware level key detection and that?
