Here at work I've been called the shortcut king and so my employer asked me to develop a short cut competition/quiz with encentives/rewards so the rest of the employees can be more efficient. Anyways, I came across a shortcut that seemed very peculiar. When I hit option shift z, my layer or brush turns to the blending mode of "Pin Light" - do your PCs do the same thing. I've tried to change this setting to a mode that I use more often by visiting the Edit Keyboard Shortcuts, but it is unavailable to change. Do you have any ideas on how to change this or, why was it included as a shortcut?
