Diagonal movement keystrokes

I just got a Stream Deck MK2. I have programed the key commands for X, Y and Z
horizontal and vertical movements.
What keyboard commands do I use to move diagonally? ( X+Y+, X+Y-, X-Y+, X-Y- )

They are unset by default - you’d need to configure them yourself if you want to use them. All shortcuts can be found in preferences.
