Can I listen to a specific section of the script?

Yes. To loop a section:

1. Swipe right on the line where you want it to start.
2. Tap the orange arrow → to confirm the start point.
3. Scroll down to the line where you want it to end.
4. Swipe right again and tap the orange arrow ← to mark the end.
5. The section will loop and only that part will be illuminated.
6. To reset, swipe right on either arrow and tap the red Reset tag.
