The Fn button is like a 'shift' key. Just as you would press <Shift> and a letter to get a capitalized letter, you press <Fn> and a function key at the same time ( <Fn><F1> or <Fn><F2> and so on) to use the secondary function for that key. For example, on one of my laptops, the <F2> key has an icon for 'wireless' (looks like an antenna). If I simply press <F2>, I will activate the function for <F2>, but if I press <Fn> and <F2> at the same time, I will turn on my wiress adapter.

<Fn> all by itself does nothing.

Hope this helps.
