Locking and unlocking layers

You can lock layers to protect the objects on those layers from changes while keeping them visible. A closed padlock icon next to the layer name in the Layers panel indicates a layer is locked; an open padlock icon indicates it's unlocked.

To lock or unlock a layer, do one of the following:

In the Layers panel, click the padlock icon to the left of the layer name.

To lock or unlock a range of contiguous layers, drag through the padlock column.

To lock all layers, Control-click (Windows) or Option-click (Macintosh) a padlock icon to the left of any layer name.
