You can change a parameter for all active trackers at once. For example, you can change the dimensions of the tracker box for all trackers or set Fixed to off for all trackers, by selecting Gang, from the Tracker Selection box. Inversely, it can be useful to hide all but a selected tracker, to edit its tracking path, for example. This is achieved by selecting Solo, from the Tracker Selection box. By choosing Selected, only the selected tracker is affected, but the other trackers are still displayed.
