Navigation controls
are available to enable you to move backward and forward through the
dashboards that you have opened. The controls include forward and
backward arrows for sequential navigation, as well as a history list
that records the flow of navigation between dashboards.
In the dashboard portlet,
navigation support is available only for dashboards that are linked.
The navigation controls are not displayed when the portlet initially
loads. However, when you activate a link from one dashboard to another
in the portlet, the navigation controls are displayed and can then
be used.
