Hard time changing elevations

There needs to be an easier way to move up floor elevations w/ the cursor. Very tedious right now. Really like the way the game Phantom Doctrine incorporates a single key to change elevation

You can change between floor elevations with the mouse wheel. There should be keys to do it too, but they don’t appear to be mapped at the moment.

I am using ‘z’ and ‘c’ to go up/down a level view
