The other trick you can do, which is the method I use, Is to simply toggle the Infopanel until it says "Carbonite" then just hit your map hot key twice. In my case I still have it bound to "M." So I would hit M once, Carb map would maximise, then hit M again, Carb map would minimize back into the correct panel.
This method works for me simply because I primarily alternate between Skada and Carbonite. Which those two happen to be one right after the other in the InfoPanel, so they are just a left/right click away
