I just forgot how to associate the objects with the charms. Some objects can be charmed by putting the "orbs" into slots. How to we open the object up again to put the "orbs" into the slot thus charming the object?

I used to be able to do this but I just reinstalled the game and now I can't seem to remember how it's done. The manual doesn't seem to cover it.
