What is the main function of the navigation bar?
A navigation bar helps readers in selecting topics, links or sub-topics of their interest. Using a navigation bar, users need not enter the URL of the specific webpage, as this is automatically taken care of by the navigation bar, with the navigation sections having embedded the necessary links of the webpage.
How do I hide the navigation bar?
The navigation bar is pinned by default. If you want to view files or use apps in full screen, double-tap the Show and hide button to hide the navigation bar. To show the navigation bar again, drag upwards from the bottom of the screen.
