wmurpht:

Run "Set Deb HW Keys" and then you can toggle the Styles and Formatting by pressing Fn (blue arrow) + Shift + "=" (top row, second from right). This is mapped to F11.

That should be in the wiki, probably. Maybe under FAQ?

(EDIT: After trying it a few times, it seems to work best when you press the Fn key and then rock your finger down to press the Shift key as well; it doesn't seem to work pressing Shift first)
