In Actions & Traits, there are multiple categories:
  • Actions (all your actions)
  • Role (role actions that apply to all classes of your role)
  • Traits (think of them as buffs mostly, or mechanics that influence how your abilities function)
  • Performance (for bard music)
  • Orders (for chocobos)
  • General (these are general actions, available to all classes)
Within the Actions category, there is a button at the bottom-right to switch the display mode. One of the display modes just lists all actions (including ones you don't use at higher levels), while the other displays only the most upgraded version and shows what they combo to, to make it simpler to understand.
