   If you drop a Handle on top of an object, that object is automatically assigned to both the Manipulate TR and Follow fields in the Handle settings.

4. Assign any objects that you want to manipulate the translation, rotation, or scaling exclusively to the Manipulate Translation, Rotation, and Scaling fields. See Manipulate objects.
5. Alt-drag an object or objects into the Handle settings and drop it in either the Manipulate or Follow fields.

You can also drag a Handle into an empty space in the Viewer window and then assign objects to both the Manipulate and Follow fields. The Handle appears in the Viewer window as a line with a round knob protruding from of the Follow object.
