Elements can become driven with either components or ProtoFlux. With components, most drivers are found under the Transform/Drivers or Relations categories. With ProtoFlux, while holding the ProtoFlux Tool, one can drag out a field from an inspector, open the context menu while still holding the field, and choose the "Drive" option. This will create a Value Field Drive or Object Field Drive node to drive the value of the field. Other sync elements that are not derivations of the SyncField type can not be driven in ProtoFlux at this time.
