Use the Navigator palette for precise movements (CS/CS2/CS3/CS4/CS5)

When you need to edit fine detail in Adobe Photoshop, it's helpful to magnify the area with the Zoom tool. Doing so, however, makes it difficult to know where you are in the image. You could expend time and energy scrolling around, trying to find a particular image area, but there's a better way. At a time like this, you need the Navigator panel. To show this panel, choose Window > Navigator. A thumbnail of the entire image appears in the palette and a border (red, by default) frames the area in which you're working. To quickly move to another area in your image, simply click and drag the frame to the image area in the Navigator panel.

You can also zoom in or out on the framed image area using the Zoom slider, the Zoom text box, or the Zoom In and Zoom Out buttons, all of which are located at the bottom of the panel. To quickly zoom in at 1600%, the maximum magnification level, [command]-click ([Ctrl]-click in Windows) on the frame. See how easy it is to get where you're going when you know where you are?
