One thing that would really, really help in the ingame Map Editor:
Map +/- to hop to the next/previous province number.

Or any other type of key combinations, like >/< or ,/.

Since editing a map or starting it from scratch involves looking at all the provinces, you have to hit the # key all the time for every single province right now, to make sure that you didn't miss any. New hotkeys would help a lot here.
