Locking and unlocking a layer


    The Lock switch prevents accidental selection of layers that you do not want to alter. When a layer is locked, you cannot select it in either the Composition or Timeline windows. If you try to select or modify a locked layer, the layer flashes in the Timeline window.

    When a layer is locked, the Lock icon (the Lock icon) appears in Features panel, which appears by default to the left of the layer name in the Timeline window.

To lock or unlock layers:

    Do one of the following:

    • In the Timeline window, click the Lock switch for the layer to place (lock) or clear (unlock) the Lock icon (the Lock icon).
    • Select one or more layers in the Timeline window and choose Layer > Switches > Lock.
    • To unlock all layers in the active composition, choose Layer > Switches > Unlock All Layers.
