The menu bar is above the content pane and consists of two rows of tabs.
The top row displays the tabs you can open through the navigation pane. These primary tabs appear in the sequence in which you open them.
After you click a primary tab, the secondary tabs associated with it appear in the bottom row. Click a secondary tab to display it in the content pane.
In both the top and bottom rows of the menu bar, if the number of tabs exceeds the viewable space, the system displays left- and right-pointing arrows. Click an arrow to scroll to the required tab.
To reduce the number of tabs on the top row, you can click the X on the right corner of a tab to remove it from the row. The following figure shows a sample menu bar.
