# Day 117 · Back and finish are useful too

“Go back. Choose again. Finish when you want.”

## Set up

Explore navigation without a loop that traps the reader. C11's toy repair guide has LOOK and ASK pages; it promises no real repair. 15–20 minutes, with a one-return option.

Use scrap paper and three broad cards, or a familiar locally approved device. A short chosen part is enough. A wanted helper reads or constructs exactly as directed; name who chooses and who operates.

## Run the session

1. Read the complete START and destinations.

2. Try a choice, then Back.

3. Check the actual visible page is START, not a secretly cleared show.

4. Try the other choice if wanted.

5. Use Finish to close the run and return focus to the start control; retained authored work stays.

6. Explain Clear is a separate choice that removes current/kept work only after inline confirmation.

## Choose a route

- 117a: Keyboard Enter/Space selects a choice and Back/Finish returns reliably with meaningful focus.

- 117b: A broad Back card asks a paper operator to show START again; a Finish card ends the run without discarding the authored cards.

- 117c: Partner-assisted selection uses an agreed “back/finish” signal, honoured immediately without requiring another branch. All explore control of a run; stop/rest is not an incorrect answer.

## Notice and next help

If Back is confused with changing a link, place one ordinary rule beside the untouched page and show exactly which state changes. No autoplay, surprise sound or irreversible pupil action.
