SUPER-FAST INCHES TO PIXELS

Want to change the unit of measurement for your image? Don't go digging through Photoshop's menus for the Preferences dialog; just Control-click (PC: Right-click) on Photoshop's rulers, and a pop-up menu will appear with a list of measurement units. Choose the one you want, and your rulers will instantly reflect the change. If you feel you must access the Units & Rulers Preferences dialog, just double-click anywhere on one of Photoshop's rulers and the dialog will appear.
