In the PlayStation 3 version, players can choose commands using the d-pad and shoulder buttons. The d-pad corresponds to the four horizontal lines at the bottom of the screen. Commands are assigned to the four directions. The L2 and R2 buttons can be used to switch between groups. Up to eight commands can be implemented directly by choosing with the d-pad and pressing buttons.
Macros can also be set. If you press L2 and R2 at the same time, you’ll be able to choose directly from a different palette. Up to eight can be registered to a palette. But even though it says eight, it’s not common throughout a class. Each class can register sets independently.
Thanks, Game Nyarth.
