Hehe, I bought meself the Executive Edition 2.0 keyboard and mouse just a tenday ago, and I'm muy happ with the product. It's wireless, because rechargable batteries are the only thing it needs, just 5 AAs. I've had no problems using the Microsoft Keyboard mapping system, the only thing that bugs m is that I can0t disable the Sleep button.
Anyways, Try going to the folder you want, copy the path, and paste it directly into the target field of the key mapping ... thingy.
About the tilt, however banal it might seem, Stormy's suggestion is the only way to go now... too bad the tilts aren't scalable, I've seen such keyboards a few years back and never again..
