MIDI Keyboard shortcuts don't work?

I have a Komplete Kontrol M32 midi keyboard to use for notation. The problem is, it doesn't appear to be fully supported by Musescore. Note input works, but I can't assign shortcuts to any of the buttons on the keyboard other than "play" and "stop." Is it really not supported fully by the software, or am I missing something? If it's the former, then that's incredibly frustrating.
