Some days you want every word exact. Other days you want to paraphrase and keep going. Line detection sets when Offbook moves past your line: word-perfect, forgiving, or only when you say so.

## Transcript

Line detection decides when Offbook moves past your line. Open Scene controls to set it.

With Auto, Offbook moves on when you finish your line. Drag How exact to the left for word-perfect lines, or to the right to be more forgiving.

With Manual, Offbook waits for you. Say next line, or press Enter, when you want to move on.

Let's try it.

Your line is done, but the scene holds until you move it on.

To go back to Auto, click Turn off manual, or choose Auto in Scene controls.
