The ticker for an interactive television system has navigational features, including a feature to lock elements of the ticker topics dynamically from the display screen while the ticker is being presented and without the need to navigate to a static preferences screen. This allows the user to view only ticker elements of interest, where the ticker loops through a specific category, subcategory, or item only. Locked ticker elements are readily re-included without the use of a static preferences screen by performing additional navigation.
