How do I move a selection a certain number of pixels in a given direction?

If it's a relatively small distance, just use the Move Selected Pixels tool (selection w/ its contents) or the Move Selection tool (just the selection) and then press the arrow keys to nudge it around. Hold Ctrl to move by 10 pixels at a time.
