Tip: You can show the Timeline on a second display, providing a larger workspace for
manipulating the timing of objects. For more information, see View the Canvas or Timing pane
on a second display on page 96.

Manage Timeline layers
Manage Timeline layers overview
The Timeline layers list mirrors the Layers list in the Project pane and displays your project
objects (groups, layers, lters, behaviors, masks, and so on) and their stacking order. Keyframes
applied to an object can also be displayed. In the Timeline layers list, you can reorder objects.
This change is immediately reected in the Layers list in the Project pane. You can also lock tracks
to prevent further editing of those tracks and disable entire tracks to omit them from view in
the Canvas.
Enable Timeline tracks
To the left of each track in the Timeline layers list is an activation checkbox that turns that
track on and o. When a track is turned o (disabled), it is ignored in the Canvas. Not only can
you turn video or audio on and o, you can also disable or enable eects such as masks, lters,
and behaviors.
