Nudging 10 Pixels At A Time
As you know, as long as you have the Move tool (V) selected, you can move (or nudge) your current layer using the Up/Down/Left/Right Arrow keys on your keyboard. For every press of an Arrow, it nudges your layer 1 pixel in that direction. However, if you hold the Shift key and use the Arrow keys, it nudges the object 10 pixels at a time.
