The main menu holds the actions that are not credentials: backups, screen/layout settings, dangerous options (factory reset) and firmware info. This guide shows you how to get there and how to move inside it.Documentation Index

Route A — From the first credential
When you’re on credential 1, Left opens the menu directly.
Route B — From the last credential (via “Add New”)
If you’re near the end of your list, another way is Right repeatedly: after the last credential the “Add New” screen appears, and another Right jumps to the menu.
Menu screen
Once inside, you see four options in the root menu. The invertedMENU bar occupies the leftmost 10 pixels as a visual marker.
| Item | What it does |
|---|---|
| Backup | Submenu with Import and Export credentials over USB serial |
| Settings | Rotate screen, UI language, keyboard layout and re-launch tutorial |
| Danger | Factory reset (wipes everything) and bootloader mode (for reflashing) |
| Info | Firmware version, serial number and status |
Enter a submenu
For example, inside Settings:
| Item | Action |
|---|---|
| Rotate screen | Rotates the display 180° (controls flip too) |
| Language: XX | Cycles UI language (Spanish ↔ English) |
| Keyboard: XX-XX | Cycles the USB keyboard layout |
| Tutorial | Re-launches the first-boot wizard |
< Back | Returns to the parent menu (equivalent to pressing Left) |
Leaving the menu
From the root menu, pressing Left takes you to the “Add New” screen (jumping one credential back), and another Left to the last credential. Pressing Right takes you directly to the first credential.| Action in root menu | Result |
|---|---|
| Left | ”Add New” → another LEFT → last credential |
| Right | First credential |
| Up/Down | Navigate items |
| Center | Enter submenu / run item |
Navigation is circular: credentials → “Add New” → menu → first credential → … No dead ends.
