Alternative Regions
An alternative region is one of a collection of regions that occupy the same space in a window where only one region can be displayed at any time. You can identify an alternative region by a poplist that displays the current region title, which sits on top of a horizontal line that spans the region. You can choose to display another alternative region by clicking on the poplist and selecting another region name from the list. The region updates to display the fields of the new alternative region you choose.
