Expanding and collapsing all groups and effects

In this movie I'll show you how to both expand, and collapse every single group …as well as every single layer effect and smart filter inside the layers panel. …So the idea is this once you start amassing a ton of layers inside of a …document things can get very gnarly here inside the layers panel with some groups …open and some group closed and some effects expand and others collapsed and …so forth. And typically what you do is you just …expand and collapse one item at a time. For example, I'll go ahead and scroll up …my list here, and I'll the little triangle there to twirl the eye bags …subgroup closed. And then, I'll continue to scroll up the …list and I'll twirl close the eyes group that contains that subgroup as well.…

And now everything's nice and tidy inside the panel. …Now, if I were to expand just the eyes group then I would reveal the contents of …that group but that subgroup would remain closed because that was its last state. …What if instead, you want to expand everything? …
