Use layers to apply an effect to multiple objects. You can edit, hide, and lock objects within a layer.

From the Layers panel, you can perform one of the following actions:

• hide or view a layer in the document window
• copy, duplicate, delete, and create layers
• merge and rasterize layers

You can edit objects only for the active layer.
