Flipper Zero is controlled by a 4-button directional pad with the ok button in the center and the back button beside it. An RGB LED provides multi-color notifications. This documentation labels each Flipper Zero button with an icon and a unique name:

• :up: UP
• :left: LEFT — also used for reboot
• :right: RIGHT
• :down: DOWN
• :ok: ОК — also enter in the Main Menu
• :back: BACK — also cancel, keypad unlock, power on and reboot

If the Flipper Zero firmware freezes or works incorrectly, you can reboot the device by pressing :left:LEFT + :back:BACK simultaneously. This is a hardware reboot that triggers the CPU to restart firmware. Read more about Reboot modes

Desktop — is the name of Flipper Zero's main screen, Dolphin spends most of the time on this screen. There is a status bar on the top of this screen with various notifications: battery charge gauge, SD card status, Bluetooth info etc.

From the Desktop you can directly navigate to four quick access applications:

You can only enter Quick Access Apps from the Desktop screen, the keypad must be unlocked.

Archive is an application allowing quick access to your saved keys and remotes. For example, launching emulation is faster from the Archive than it is from the main menu. Besides emulating, you can rename and delete keys, and you can add any item you have to favourites in the Archive app.

Archive displays all the saved user keys, signals, remotes and scripts. Items in the Archive are sorted by protocol, with each tab containing items of a particular type. The :right: RIGHT and :left:LEFT buttons are used to navigate between tabs.

Tabs in the Archive app:

• Favorites — pinned keys for quick access
• Sub-GHz — radio remotes & signals in the Sub GHz range
• RFID LF — low frequency tags RFID 125 kHz
• NFC — high frequency 13,56 MHz tags NFC
• Infrared — infrared remotes & signals Infrared
• iButton — Dallas Touch Memory keys iButton
• Bad USB — scripts for USB attacks
• U2F — 2FA (2-Factor authentication) keys
• Browser — allows managing files in the Internal Flash memory and on the SD card

Press :ok:OK to open the context menu in the Archive:

1. Run in app —  launches emulation, same as selecting "Emulate" from the original application's menu
2. Pin — adds the selected item to the Favorites tab for quick access
3. Rename — changes the name of the file
4. Delete — deletes the file from your device

The Favorite App feature allows you to set any app for quick access right from the Desktop. For example, you can set the NFC app as favorite and now you won't need to look for it in the Main Menu each time you want to read a card. Pressing the :left:LEFT button while on the Desktop launches the Favorite App.

You can select the favorite app in the Settings menu: Main Menu → Settings → Desktop → Favorite App
