Viewing and opening hidden tabs

Once open tabs reach the horizontal limit on the home screen, additional open tabs are moved to a drop-down menu. The number indicates how many additional, open tabs are in the drop-down menu.  

To view and open hidden tabs:

1. Select the hidden tab arrow (  ).
   The resulting drop-down list displays all open screens that do not fit horizontally on the tab row.

2. From the drop-down list, select the tab to open.
