Sub-skills have a variety of uses. Such as: Expressing a user's emotions, shortcuts for attacking and picking up items, auto-running and also for setting up a player market.
You can perform one of the sub-skills by pressing B (sub-skills window shortcut) and then by clicking the skill you wish your character to perform.
