Special Effects Values

Ok, so I recently started messing around with the Special Effects in the World Editor (I was lucky enough to find a list of all of them) and have come across a problem. Whenever I make one, there is a value named overhead, which obviously displays the effect...overhead. So, my question is, does anyone know any other values? So I can actually make an effect on my unit, rather then above him? :confused:

Overhead, Head, Chest, Feet, Origin, Left Hand, Right Hand, Weapon (for Heroes) is what i know. There are even more, ton more, but i forget the post with them in it

Use Origin for the string, it puts the effect right where the units standing.
