To help you get around on your Kindle Fire HDX, an Options Bar of navigational icons is displayed along either the bottom or side of the touchscreen. The toolbar remains permanently visible in some apps and gets hidden after a few seconds of inactivity in others. Since the Kindle Fire HDX lacks a physical Home button, however, the toolbar is necessary for getting around on the device.
Exposing the Options Bar
The Options Bar gets hidden to prevent distraction while using apps with full-screen functionality -- during video streaming with Netflix, for example, or while playing a game of Candy Crush. In these instances, a hidden Options Bar can be exposed by swiping the small tab at the right or bottom edge of the display inward. The Reading app is an exception -- it only requires a tap on the screen to expose the toolbar.
Options Bar Icons Explained
The Kindle Fire HDX's Options Bar includes icons that are easily identifiable by even the most novice users. The house-shaped icon navigates you to the Home screen while the left-facing arrow returns you to the previous page. Tap the "Menu" icon, which looks like an open box with three horizontal lines, to reveal additional options or settings that may be available in the app you're using. The magnifying glass launches the search function and the keyboard icon hides the onscreen keyboard.
