I was wondering how I copy selected paths of a shape in PS CS6.
How can I copy all of the selected paths, not just one?
Select the paths as you normally would using Shift and click with the black arrow path tool, then Ctrl C to copy and Ctrl V to paste. There's no need to use any other modifier keys.
If you want to copy multiple paths within the shape layer by Alt-dragging, press Alt, start to drag, then add Shift to constrain the movement.
