: Scrubbing Audio in After Effects
To hear the audio while you’re dragging through your After Effects timeline, hold down the Cmd (Mac OS) or Ctrl (Windows) key while dragging.
While not as good as a full preview, it can help you find your place quickly. You can improve audio scrubbing by turning off the visibility for layers with video- or processor-intensive effects.For more Adobe tips, check out Creative Cloud User.
