nTouch

nTouch is a software replacement for iTouch that indeed does run under Windows Vista. nTouch contains a unique feature not included in the original iTouch software: the ability to make the Fn (F1-F12) keys work as Fn keys (and not custom actions such as New, Undo) without having to press the Fn Lock key.

With a simple interface, you will be able to easily define your custom keys. You can choose to load the program automatically when Windows starts and always to use the Fn keys.
