Apple UK keyboards – where’s the #?!

Well here’s an interesting one that I’d never noticed before…

The genuine Apple UK keyboard doesn’t have a # (hash) key on it!
The secret is to use ALT 3 which gives a ‘#’ in OS X Snow Leopard.

It turns out that it’s not that easy if you’re running a Remote Desktop Connection (RDC) into a machine running Windows. Anyone any idea how to fix?
