I have been using Photoshop since version 2 (the dark ages of computer design) and just had Lori point out a cool feature I never knew existed!
I know PowerPoint is our topic, but I work in Photoshop virtually everyday preparing images for templates and presentations. In this case I was moving back and forth between PPT images that are measured in pixels and a print layout that was measured in inches. So, I was constantly going into the preferences and changing the rulers until Lori came over and pointed out a better way.
If you RIGHT-CLICK the ruler in Photoshop, it can instantly (and easily) be changed!
