Talk: When turned on, the viewer will talk: i.e. it will send a position message to any viewer that is listening. It syncs two viewers if the other is listening (described below). Turn this off if you do not want the viewer to send any messages to any other viewers.

Listen: When turned on, the viewer will listen: i.e., it will receive any messages from any viewer that is talking. For example, if a talking viewer in scrolled in time, any listening viewer(s) will scroll in time as well. The seismic displays will be synced. Turn this off if you do not want the viewer to receive any messages from any other viewer.
