81 Zoom In and Out with the Overview Palette
Some changes you'll want to make to an image will involve working in a small confined area. For example, perhaps you want to remove a small mole or other distraction from a person's face. To do that, you can use the Clone tool, but what if you can't see the area you want to fix all that clearly? You could zoom in, of course, but it might be nice to be able to view the changes as you make them, using a more zoomed-out view. Of course, there's always the Overview palette and its small image thumbnail, but your tiny changes might not be noticeable in that window. What you need is the ability to quickly zoom in on your work while still maintaining the big-picture view of your changes. To accomplish this task, you use the Magnifier palette.
Display the Magnifier Palette
Choose View, Magnifier from the menu bar or press Ctrl+Alt+M .
Magnify the Work Area
Move the mouse pointer anywhere over the image to magnify the area directly beneath the pointer.
