There is a scene browser to use for this... You can use named objects or styles. When you slect something, if you clcik the name in the upper right, you can name it. Then it will be an object down in the objects section. The eye is for hide/show, and there is a far right dot for selection. Think of styles like layers, and the show/hide/selection is the same. Types will target edges/solids/faces etc....
