Module help 

The help overlay: one screen’s keys from the key registry (datui_cli::keys), grouped by task, the keys of every screen last.

/ narrows the lines to those whose key, label or description holds what is typed. Enter closes the help and presses the key on the selected line, as the next key the app takes: Help::key answers HelpKey::Press, and the App hands that key back to the event loop as its follow-up AppEvent::Key, so it takes the path a typed key takes (held while busy, replayed in order) rather than a parallel set of actions.
