What does it do in relation to figure actors, create a child bone grouped with a selected geometry and parent in the hierarchy? Can it be any old object, is there a browser, or is it from a preset selection menu?

You get a menu that lists every item in the scene, including whatever body parts to figures that are present. Select whichever item you need it to control and press OK. It doesn't create a new bone. It's listed as the last item in thefigure hierarchy when you set it to control the body.
