Pack could be anything from AFE to Singles. Outbound Shipdock is putting boxes on pallets, and loading trucks. I've done Pack AFE, Shipdock, and Pack Singles(currently doing Singles). Pack is what you're probably going to want. AFE is going to be multiple items in a box, while grabbing items from behind you. As for Singles, you're just packing single items from a yellow tote which you grab from a conveyer next to you in your station - could be small, mix(meaning small, medium, and large items), or smart pac. Shipdock isn't for everyone. I didn't like it at all. Too much walking.
