How to: Change the position of a tab on the ribbon
You can change the order of custom tabs on a ribbon by using the Tab Collection Editor. You can position custom tabs before or after a built-in tab on the ribbon. A built-in tab is a tab that is already on the Ribbon of a Microsoft Office application. For example, the Data tab is a built-in tab in Excel.
