The Query Spotlight portlet cannot rewind and does not use the rewind toolbar. The Control Rewind button in the Query Spotlight portlet is a toggle that enables portal rewind for portlets that support the rewind function on the same page. When rewind is enabled, the time marker in Query Spotlight sets the time and date in the rewind toolbar and controls the time and date for data in the other portlets. This allows you to investigate how metrics compare across portlets during the same time frame.
When Control Rewind is toggled off, the time marker no longer controls the date and time for data in the other portlets and portal rewind is controlled from the rewind toolbar.
