Every screen's keys are constant tables in lib/core/src/app_keys.h (52 of them, each under an `// id: Title` comment). An App's help() picks the table of the state it is in. site/tools/gen_dev_docs.py reads the same file and writes site/data/keys.toml; the `keys` shortcode shows a screen's tables on its guide page, and /guide/keys/ shows all of them. The Site job fails when the data file is out of date or a page asks for a table that doesn't exist, and now also runs when app_keys.h changes. A key added to an App shows up on the website without anyone editing a page.

The Wi-Fi tools show what the radio hears now: they scan for the networks around you and list them. They do not join anything.
The menu
Three entries: Networks nearby, Channel occupancy and Signal tracker. Pick one with the arrows and press Enter.
Networks nearby
A list that refreshes by itself: each network's name (or (hidden)), channel, signal in dBm and security. The top line says how it is sorted and filtered.
| Key | Does |
|---|---|
| s | Sorts by signal, channel or name, in turn |
| o | Shows only open networks |
| h | Hides the hidden networks |
| w | Shows only the strong ones |
| l | Starts and stops logging |
| Enter | Opens the Signal tracker on that network |
Logging adds each scan to /wifi/scans/<date>.csv on the SD card, one row per network, once the device knows the date; LOG and a row count show while it runs. Logs stop when the card passes 90% full.
Channel occupancy
One bar for each of the 13 Wi-Fi channels shows how busy it is: how many networks use it, and how strong they are. The top line counts the networks and names the quietest of the three channels that don't overlap, 1, 6 and 11. It is the quick answer to "which channel should my router use?". ` (Back) returns to the menu.
Signal tracker
Follows one network: its name, address and channel, then the signal in dBm in large type, a strength bar, and a graph of the recent readings, so you can walk towards the strongest signal. m turns audible clicks on and off. If the network is no longer heard the screen says lost. ` (Back) returns to the list.
The keys, as the device lists them
What Fn + h shows on these screens. These tables are generated from the firmware's own lists, so they are always the current ones.
