What the tab bar allows you to do
The Tab bar appears at the top of the right hand panel, just below the basic details of the selected item. The tab bar allows you to work with all the available details of the selected item. By default the General details are displayed when you select an item.
User permissions may restrict your use of individual tabs on the tab bar.
You can navigate the tabs for the selected item by using the left and right arrows on either side of the tab. The tabs that are available depend on the item that you have selected.
Alternatively, you can select the tab and display a list of all the tabs and then select the tab you require.
