I'm used to having the `Control` button at the bottom left corner of the keyboard. It's a little annoying to be pressing `Fn` + `Tab` when I wanted a `Control` + `Tab` and the position of the `Control` button in the new Mac keyboard layout is just very uncomfortable for any finger to reach.

Does anybody know how you can make the `Control` and `Fn` buttons change function like how you can change the modifier keys in System Preferences?
