Stuart,
Wow. Thanks. I'm on a Mac, so it's a little different, but you got me there:
HD\Users\(username)\library\preferences\graphisoft\AC 8.1.0
I actually don't need to transfer the keyboard short cuts today (but i will in the future) so I don't know yet which file to copy, but it's definitely there.
Thanks so much. I don't know what I'd do without this Forum!
