Expose Commands
Motion’s expose key commands provide a way of viewing multiple layers at once,
exploding and rescaling them.
The expose commands allow you to access all layers in a project in the Canvas without
having to drill down into the Layers list or Timeline. Expose commands also let you select
inactive layers at the playhead’s current position or jump to a selected layer’s In point.
There are two expose commands: One displays all layers in a project, and the other displays
only those layers active at the current position of the playhead in the Timeline.
Exposing Active Layers
The Expose Active Layers command lets you view the layers that are active at the position
of the playhead in the Timeline.
To expose layers that are active at the playhead position
1 Click anywhere in the Canvas.
2 Press X.
Layers active at the current position of the playhead temporarily scale down and spread
out over the Canvas. Each active layer is represented by a white frame in the Canvas.
Moving the pointer over a frame reveals the layer’s name.
3 Select the layer to work on.
The elements move and rescale back to their original positions; the element is selected
in the Canvas; and the playhead moves to the first frame of the selected layer.
