Those who knows me will know that I love to explore and fiddle with my Macs and wacom. I highly recommend this video on how you can fully utilise your wacom tablet by setting up shortcuts for those side buttons. Very useful in Photoshop for zooming and calling up functions like change brush sizes or special menus. If you keep going to the top menu bar for something, setting up a shortcut to those side buttons will make your job flow easy. Please feel free to share your workflow or tips.
