ZOOMING IN THE FILTER GALLERY

Although you'll find a pop-up menu for choosing your preview zoom percentage in Photoshop CS's Filter Gallery, there's a much faster way to zoom in. Just use Command-+ (PC: Control-+) to zoom in, and Command- (minus) (PC: Control-) to zoom back out. Also, if you want a larger preview area, just grab the bottom right-hand corner of the preview window and drag outward, and the window will expand, giving you a much larger preview. Also try pressing Command-0 (PC: Control-0) and the Filter Gallery dialog will expand to take up your full screen.
