Overlay updates for Skillshare Photoshop class

Some of the feedback that I have received from my Photoshop class on the basics of opening and editing an image in Photoshop talked about my fairly Mac-centric shortcuts. It's true that I have been working mostly on the Mac for a long time, but that's really no reaosn to leave others out in the cold. I'll make the overlays in Photoshop and build out to Final Cut.
