How to use the 15 special keys and 11 keyboard shortcuts on the official wireless keyboard for Amazon Fire HD 10 2021 (and Fire HD 10 Plus)?

The Home key allows you to return to the home screen of the Fire HD tablet. You can use it at any time to leave an app. It is equivalent to tapping the Home button in the navigation bar.

The Search key directs you to the search box. You can type the search phrase to search. The search bar is the destination on the Home screen of Fire HD 10 2021 (and Fire HD10 Plus).

But if you are using an app. The behaviour may be different. For the pre-installed Amazon apps, it can search inside the specific app. It can be even context-sensitive. For example, if you are reading a book in the Kindle app and press the Search key, you can then search the contents of your books. If you are on the Store page or Library page, the Search key will not function at all, although there is a search bar on these pages.

Third-party apps, especially apps installed from Google Play Store, the behaviour varies. For example, the Search key works well on Chrome browser and YouTube, but not in the Play Store app.

The Back key is equivalent to the on-screen back button in the navigation bar. You can press it once to return to the previous screen. For most apps, if you keep pressing the Back key, it will exit (close) the app.

If you are on the Fire HD 10 Home screen, then pressing the Back key will eventually bring you back to the Home (the middle panel) of the Home screen.

The Open File folder key, aka File app shortcut key, lets you open the File app on the Fire HD 10 2021 or Fire HD 10 Plus.
