Adobe PhotoshopDid you know that when you’re working with multiple Photoshop documents open at once that you can zoom them all to 100% with a simple keystroke? By holding down the Shift key and double-clicking the Zoom tool in the Toolbox, all your document views will be set to 100%. Pretty handy when you’re evaluating several images at once. Of course, this assumes you have each image open in its own window, rather than CS4’s tabbed window mode.
