It there a way to loot quest items or items without resorting to switching to 2nd toon to do it then 3rd toon.

I am new to the scene and running 2 shaman on 2 separate pcs. I would like to have the second shaman loot corpses for its quest items without having to do it via the second pc mouse, since I control both characters from the main pc keyboard/mouse.

How do you guys do it?
