Maybe this works:
Code:
* IsSlotUsed(*luaindex* _actionSlotIndex_)
** _Returns:_ *bool* _used_
* GetSlotCooldownInfo(*luaindex* _actionSlotIndex_)
** _Returns:_ *integer* _remain_, *integer* _duration_, *bool* _global_, *[ActionBarSlotType|#ActionBarSlotType]* _globalSlotType_
* IsSlotUsable(*luaindex* _actionSlotIndex_)
** _Returns:_ *bool* _useable_
