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.
