The Navigator Panel in Photoshop Elements 12
The Navigator panel in Photoshop Elements is a handy tool to keep open when you need to zoom in and out of a photo while editing images. It allows you to zoom on a particular part of a photo while viewing a thumbnail preview of the entire image in the Navigator. You can do all your zooming in this panel — and you can keep it open during your editing session!
To open the Navigator panel, choose Window→Navigator. The panel opens in a floating window, as shown in this figure.
At the upper right adjacent to the slider, a readout displays the current zoom percentage. You can move the slider left to zoom out of a photo and right to zoom in on a photo. In the center of the panel, you see a view displaying the entire image and a red rectangle displaying the area corresponding to the zoom view in the Image window.
The rectangle in the center of the panel can be moved around the Navigator panel just as you use the Hand tool to move around an image. The lower-right corner is dragged out or in to size the panel larger or smaller, respectively.
You can quickly resize the zoom area in the Navigator panel by pressing the Ctrl key (Cmd on the Mac) and drawing a rectangle around the area you want to zoom.
