The locked object’s bounding box in the Canvas turns red to indicate that it’s locked.
Collapsing and Uncollapsing Layer Hierarchies
Layers and objects in the Layers tab appear in a hierarchy that shows which objects are
nested inside which layers. Nested objects and layers appear underneath and indented
to the right of the layer they’re nested within.
To make the Layers list easier to manage, you can collapse all objects that appear
nested within a single layer using that layer’s disclosure triangle. Collapsed layers
appear as a single line in the list, and can be moved or nested like any other object.
Each layer’s thumbnail displays a preview of the entire composite within, making it
easy to see what’s nested inside.
To open or collapse a single layer, do one of the following:
m Click the disclosure triangle to the left of that layer’s name and icon.
m Press the Up and Down Arrow keys to navigate up and down the Layers list, then press
the Right Arrow key to open a layer, or the Left Arrow key to collapse it.
Renaming Layers
You can rename the layers and objects that appear in the Layers tab to further organize
your media and make each layer and object’s purpose easier to identify. When you
rename an object, the original name of the source media file on disk remains
unchanged. Also, changing an object’s name in the Layers tab does not change the
name of its corresponding object in the Media tab. You cannot change the name of an
object in the Media tab.
