You can add a pause statement to your lyrics to pause the auto-scroll.
This is the pause statement:
{pause:10}
Place that in your lyrics to pause the auto-scroll. The number after the colon is the seconds to pause. In the example above, the auto-scroll is paused for 10 seconds.
You can also write your pause statement like this:
{pause:1:12}
This will pause the auto-scroll for 1 minute and 12 seconds.
If you want to cancel the auto-scroll before the pause ends, you can tap the "Continue" button. Also, you can double-tap the lyrics to start them again and cancel the auto-scroll.
