InDesign Eyedropper Options
Most designers new to InDesign think the Eyedropper tool exists solely to choose a color from an image or other object on the page. More experienced users know just how powerful it can be, and much easier it can make things.

Not only can you choose colors, but you can apply fonts, styles, colors, transparency and more to other objects with simple clicks.
