You have to set the key you press to activate the map, which is found when you click on the map name (eg shields or whatever you called it).

You also need to set the key that is ACTUALLY sent to the wow clients, which based on the screenshot you did.

If you are stuck, do a Save As on your current profile, do a clear profile, click on the Wizard, follow the prompts then look at the resulting key maps. Its a great way to reverse engineer the basics.
