Hello all, this is one specifically for UK / Irish users: What exactly is the deal with the key we have between the right Apple key and the <home arrow key? It performs the same function as the Return / Enter key as far as I can tell.. or does it? Its something I've always meant to look up and I've just rooted out my manuals and it doesnt refer to it since it only shows a US keyboard. So... is there a point to it? thanks!
