Merge Selected

If your Layers palette is getting a little out of hand with way too many layers, there's a simple solution. After selecting the layers you want (see previous tip), use the Layers palette's flyout menu to choose Merge Selected and turn those separate layers into one layer with sublayers. For example, if you select three layers, each with two sublayers, and use Merge Selected, you will get one layer made up of six sublayers. The merged layer will use the name of the last layer you select.
