The SSH App opens one session to a shell, over libssh (LibSSH-ESP32 5.10.0) on mbedTLS. A server is trusted the first time on its fingerprint, and a changed key is a warning with Cancel selected. The password is typed each time and kept nowhere; or the device makes itself an Ed25519 key, whose public half is shown, written to /ssh/id_ed25519.pub and printed by `ssh status`. lib/term is the terminal: what a shell, less, top, nano and vim send, with sixteen colours, scroll regions, the alternate screen and 100 lines of scrollback. Five text sizes with Ctrl and + or -, from 60x20 to 26x8, told to the far end. The session goes on when the App is left; SSH shows in the Status Bar. `ssh user@host` in the Shell opens the App. Also: - Keys that aren't characters carry Shift, Ctrl and Alt. The terminal needs it, and it makes Ctrl+Fn+up/down in a note and Shift+Tab in Gemini work from the real keyboard. - IRC doesn't try to connect under 60 KB free: started with a session open, its TLS handshake took the heap down to 236 bytes. - libssh's own curve25519 is left out of the build (scripts/libssh_filter.py): libsodium's has the same names. Costs 292 KB of flash and about 50 KB of heap while a session is open; not started under 75 KB free. Docs: guide page, how-to, FAQ, home page, Status Bar, SD card folders, the memory how-to, README, glossary, N1 notes with Q254 to Q266 and the checks.

This guide says what the firmware does **today** and nothing else. Start with the basics (the keys, the Launcher, the first start), then read the page of any App. **On the device itself, <kbd>Fn</kbd> + <kbd>h</kbd> lists the keys of whatever screen you are on:** nothing else on a screen names them. It describes the latest release; the numbers and key names come from the firmware's own source.

**The mesh messenger is planned, not built.** The LoRa Scanner listens to Meshtastic traffic and shows it, but the device sends nothing yet: that is the next milestone and waits for a second node to test with.
|

|
|
**Three things work on every screen:** <kbd>Fn</kbd> + <kbd>h</kbd> for the keys, <kbd>Fn</kbd> + <kbd>p</kbd> for a screenshot, and <kbd>Fn</kbd> + <kbd>`</kbd> to go back to the Launcher.
|
|
|
|
**Two things keep running when you leave their App:** IRC stays connected, and an [SSH](/guide/ssh/) session stays open.
