PS4 Controller

Cross - Confirm Command, Square - Open Unit Info, Circle - Cancel Command/Close Window, Triangle - None, Start - Skip Scene, Select - Reset Game (F12), L1 - Previous Character, R1 - Next Character, L2 - Close Game (Escape), R2 - Toggle Full Screen (F4). The game's reset function defaults to F12 and cannot be changed. This is Steam's default screenshot hotkey, so you will want to change or disable that in the Steam settings.
