Tracking for beginners


I've heard some rumours about Track function. Great tool to manage movers, they say. I thought Tracking can keep mover in a position with all the parameters until there is some change of particular device in a cue maybe 50 cues later. I just tried to track a mover (112 + Track) and no miracle happend. Cobalt manual wasn't really helpful and I didn't find any article or tutorial to make this clear to me. Can you help or recommend something?

Thank you.
