When you playback a composition, Descript will auto-scroll the visible sections in the Script editor and Timeline following the playhead or active word.
If you're looking to add an auto-scroll-like effect to a text layer, check out our guides on animations and captions for more information.
Toggling on/off auto-scrolling during playback
The auto-scroll will turn off anytime you yourself scroll in either the Script editor or Timeline. To re-enable auto-scroll during playback, simply click the Jump to playhead button above the Timeline, or press Esc and your window will automatically re-center back on the playhead. Anytime you playback your composition, auto-scroll will be re-enabled.
