When retouching images (especially when checking for dust or imperfections), I like to systematically move through the document starting at the upper right, moving down screen by screen, then, at the bottom, I move over one screen and start moving up again. In order to do this, the following shortcuts can be truly lifesavers.
- The Home key moves to upper left corner, the End key moves to lower right.
- The Page Up / Page Down key moves up / down one full screen.
- Command (Mac) / Control (Win) + Page Up / Page Down moves left / right one full screen.
