how to assign actors to a specific layer?

last one for today! HA!
I need to have certain actors to be behind others but no matter to what position I drag them, the display does not update and reflect what I'm doing ...
According to google, I have to create a layer, which I did, but the only article I found does not explain how to add an actor to a layer. Unless one has to make the layer first and then what ever actor is created automatically .... nah, that would be too weird!
Anyone?
Thanks
