This may be obvious to anyone who has used Illustrator and InDesign for a while, but not everyone has done so. When you’re working on a large file in Adobe InDesign, you can zoom in on an area by holding down the Command + Spacebar keys while using your mouse to select an area on the screen. Upon release of the mouse button, the area you selected will appear larger on the screen. Add the Option key to that and you can zoom out as well.This may be obvious to anyone who has used Illustrator and InDesign for a while, but not everyone has done so.
