## Line detection modes

Open **Scene Controls → Line Detection** to choose how Offbook decides you've finished a line:

- **Auto:** Offbook moves on when you finish your line. Drag the **How exact?** slider to set how close to the script you need to be. It has four stops, from Word-perfect to Forgiving: **Exact words**, **Small slips OK**, **Own words OK**, and **Main idea**. Pick a forgiving stop for early run-throughs and Exact words once you're nearly off book.
- **Manual:** Offbook never advances on its own. You move on by pressing **Enter**, clicking Next, or saying **"next line"**. To go back to Auto, click **Turn off manual** or choose Auto in Scene Controls.

## Auto-advance on silence

With auto-advance on, the scene moves forward after a stretch of silence, which helps when you trail off or a line just isn't matching. Pick a delay from **1 to 6 seconds**. (Not available in Manual mode.)

## Word tracking

Turn on **Enable word tracking** in Scene Controls and Offbook **underlines each word of your line** as it hears you say it, so you always know exactly where you are. After the line, any word it didn't hear stays marked.

## Display options

- **Appearance:** Dark, Light, or System (follows your device).
- **My lines:** make your own lines stand out in color or with a highlight.
- **Font size:** scale the script text from 10 to 24 pt.
- **Playback speed:** set the default speed for AI-read lines; you can also override speed per line in the [scene editor](https://www.offbook.com/help-center/guides/editing-your-scene).
- **Hide start marker:** ignore the start marker and always begin from the top.
- **Theme:** pick one of six accent colors or set a custom one to change the app's highlight color.

**Tip:** Rehearsing movement or on your feet? Combine a larger text size with a forgiving **How exact?** stop and auto-advance so you can stay off the keyboard entirely.
