 ## Page keys on every page
 
-The UP / page number / DOWN keys on **every page** follow the ALL button. They're green when everything is fine, flash red when something is wrong, and turn purple if the watchdog stops. They are Companion's own nav keys converted to regular buttons (`nav_templates.json`), so presses work exactly as before.
+The **page number key** on every page follows the ALL button. It's green when everything is fine, flashes red when something is wrong, and turns purple if the watchdog stops. UP and DOWN stay normal. Which keys follow ALL is `"nav_keys"` in `config.json` (`["pagenum"]`; add `"pageup"` / `"pagedown"` to colour those too). The coloured key is Companion's own key converted to a regular button (`nav_templates.json`), so a press works exactly as before.
 
 - `python3 nav_keys.py` applies them to every page. Run it again after adding pages.
 - `python3 nav_keys.py --revert` puts Companion's built-in nav keys back.
