As the title says, I'm using a MacBook Pro to log in to my Windows 7 desktop (using "Remote Desktop Connection").

I've tried all the usual keyboard combinations to get a hash key from within Windows: Alt+3, Ctrl+Alt+3 (both left and right alt keys on the keyboard) but no characters appear.

Any ideas?

The key combination to use is Cmd + \
