ABSTRACT
To zoom in on an image, you can either click with the zoom tool to magnify, or drag with the zoom tool, marqueeing the area you wish to inspect in close-up. This combines a zoom and scroll function in one (a plus icon appears inside the magnifying glass icon). To zoom out, just hold down the A key and click (the plus sign is replaced with a minus sign). You can also zoom in by holding down the Spacebar + the C key (Mac) or the L key (PC). You can then click to zoom in and you can also zoom out by holding down the Spacebar + the A key. This keyboard shortcut calls up the zoom tool in zoom out mode and you can then click to zoom out.
