Just bought a Wacom Intuos pro to hopefully speed up my processing in LR & PS, i normally use keyboard shortcuts when in LR & PS, so when im in LR and going through a large photoshoot i use the forward and back keys to go through the photos and hit the X key to reject the ones i dont want, so what is the best way to set up the wacom so i can do this, watched a few youtube videos but im more confused now than when i started. thanks in advance
