All mouse and keyboard controls of Underrail. The game can be played without any keyboard controls, using only mouse.
-  Highlight highlights all characters and usable objects, showing their names and displaying any that are obscured by walls. Reverse Highlight simply highlights them in reverse order. If something is untargetable because it's behind another object (e.g. enemy behind a door or remains behind a desk), you can target it with reverse highlight.
-  Not rebindable.
