feature request: navigate config with keyboard

Hey, I would really like an option to navigate through config with my external keyboard.
Especially exiting the config seems somewhat cumbersome (needing 2 taps on the screen when in a menu).
Just a suggestion to improve a great app. Thanks

The issue does not name files, tests, or an entry point. Start by locating the iOS configuration screen and its keyboard or focus handling, then clarify which configuration controls and exit actions must be navigable and how completion should be verified.
