Navigating around when zoomed in
When editing images in Photoshop I often zoom in to make perfect selections. However, navigating around using the slide bars on the side of the image is cumbersome.
The next time you are zoomed into a photograph try this. Hold down the space bar and you'll get the hand tool to allow you to temporarily move wherever you need to go.
After I found this little jewel, I use it all the time now.
