VPN: a WireGuard tunnel (#8)
The device joins a WireGuard network over whatever Wi-Fi it is on: one
peer, IPv4. A client's .conf is imported from the card (/vpn/wg0.conf) and
kept in the device's settings, private key included, never shown; Settings
offers to delete the file. A switch brings the tunnel up until the next
restart, "Start with Wi-Fi" every time; it waits for the clock, which a
handshake needs. VPN shows in the Status Bar.

The protocol is esphome/wireguard 0.4.8. It calls lwIP without lwIP's lock,
which this framework checks: every call into it is made with the lock held.

What goes through the tunnel is everything (AllowedIPs 0.0.0.0/0) or the
one subnet the device's tunnel address is in: lwIP routes by an
interface's subnet or by default, nothing finer. The import says how many
ranges it can't reach.

+++ title = "Every key" description = "The keys of every screen of the firmware, as the help panel lists them on the device: one table for each screen and state." weight = 14 [extra] tag = "Reference" +++

On the device, Fn + h lists the keys of the screen you are on (and ? does, when you are not typing). This page is all of those lists at once, generated from the same source the firmware reads: lib/core/src/app_keys.h.

In the tables, ; . , / are the arrow keys (up, down, left, right): alone when you are not typing, with Fn when you are. ` is Back, Aa is Shift, and two keys separated by spaces are two keys that do the two things listed.
