Making paths with the Pen tool (P) is a skill well worth learning. These vector paths are the most accurate and clean way to make a selection of shapes with hard edges. While you’re creating a curve, sometimes you add a point and it’s not exactly where you want it. What to do? Do you delete the path and start again? Here’s a better solution: After you click to add the point and before you release the mouse button, hold down the Spacebar, and now you can drag that point to where you want. If you want to delete the last point, press the Delete (PC: Backspace) key; pressing Delete (PC: Backspace) twice will delete the entire path.
