Updating layer states
The tags are appended to comments in the Comments column in the Timeline panel.
Soloing excludes all other layers of the same type from being rendered—both for previews in the Composition panel and for final output.
If the layer is an adjustment layer, the Video switch controls whether the effects on the layer are applied to the composite of the layers below it.
If the layer is a camera or light, the Video switch controls whether the layer is on or off.
When a layer is locked, you cannot select it in either the Composition or Timeline panels.
If you try to select or modify a locked layer, the layer flashes in the Timeline panel.
