Fn+h on any screen, text fields included, and ? outside Text Entry, open a panel over the content area: the screen's own keys, then the ones that work everywhere. Every App declares its keys for the state it is in (pages, viewers, dialogs and text fields answer for themselves); the App manager opens the panel and takes every key while it is open. About 30 hint lines are gone, from every App. What stays on a screen is state. The first-start Setup keeps its hints and teaches the key; a device set up before gets one Toast, once. The guide and the FAQ open with it. `key help` over the consoles. 476 host tests (8 new). Checked on the device with key help and screenshots: the Launcher, all nine Apps and several of their states. 8.5 KB of flash and 40 bytes of static RAM. Decisions Q196 to Q203 in docs/milestones/U1.md. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EhqxQ49eCju4CzKYNjZzwT
