7. The Menus / 7.5 The Layer Menu

7.5.47 Management/Copy Group Reverse

Copy Group Reverse copies the active group, but the order of the layers inside the group will be reversed.

You can use this function to create endless animations. First you create the animation steps for the first half of the animation, then you group these layers, copy them reverse and dissolve your groups. Your animation is finished.

Note that there is no function Copy Group, because you can do this job with Copy Active Layer.
