View another area of an image

Do one of the following:

Use the window scroll bars.
Select the Hand tool and drag to pan over the image. To use the Hand tool while another tool is selected, hold down the spacebar as you drag in the image.

If your computer has OpenGL, you can use the Hand tool to “flick pan” the image in the direction you want to view. After a quick mouse gesture, the image will move as if you were continuously dragging. Enable this feature by choosing Edit > Preferences > General (Windows) or Photoshop > Preferences > General (Mac OS) and then select Enable Flick Panning.
Dragging the Hand tool to view another area of an image
Drag the colored box (proxy view area) in the Navigator panel.
