Copy or duplicate a layer

When you copy a layer, you copy all of its properties, including effects, keyframes, expressions, and masks.

Duplicating a layer is a shortcut with which you copy and paste the layer with one command. Duplicating a layer with a track matte preserves the relative ordering of the layer and its track matte.

If you have a component of a layer—such as a mask or keyframe—selected when you copy, you copy only that component. Before copying, press Shift+F2 to deselect all of a layer’s components and leave the layer selected.

To copy selected layers and place the In points of the copies at the current time, choose Edit > Copy, and then press Ctrl+Alt+V (Windows) or Command+Option+V (Mac OS).
To copy selected layers and place the copies at the same times as the originals, choose Edit > Copy, and then choose Edit > Paste.
To place copies at the top of the layer stack in the Timeline panel instead of immediately above the originals, press F2 to deselect the originals before you paste.
To duplicate selected layers, choose Edit > Duplicate or press Ctrl+D (Windows) or Command+D (Mac OS).
