Okay so it's time to ask another animation related question that no one will know the answer too (prove me wrong please).

Looking at the equip and unequip weapon animations I'm finding text key entries of the likes, Enum: Left, Enum: Right, Enum: Equip, and I'm wondering what the effect of these calls are? I don't see these in creatures with embedded weapons but only in characters and creatures who can equip a variety of playable weapons.
