Use The Spacebar To Pan and Scroll The Canvas

If you’ve zoomed into an image and you want to work in another area without zooming out and then zooming back in; you can press and hold the Spacebar on your keyboard and your cursor will turn into a “hand”, allowing you to to pan and scroll the canvas.

You can do so by clicking and dragging on the image to see a different area. Let go of the Spacebar and the tool you were using previously will return.
