I’m sure this has happened to you – you’re zooming along drawing a path around an object using the Photoshop pen tool and all of a sudden you’re running out of room – the image is off the screen. The solution is simple, press and hold the Spacebar and the cursor turns into the Hand tool so you can move the canvas around to get the next bit of the image in view. Let go the Spacebar and you’re back to working on your path.
And, while you’re there – wanna rotate the canvas so you can draw your path more easily? Easy! Press and hold R (R for rotate) then drag the canvas to rotate it.
