Transforming And Copying At The Same Time
Generally, when you apply a transformation to an object (scaling, rotating, distorting, perspective), you apply that transformation to the object itself. However, here’s a cool tip if you want to apply a transformation (using Free Transform) on a duplicate of your object, rather than on the original: Press Command-Option-T (PC: Control-Alt-T), then use the Free Transform tool as you usually would. You’ll notice that as you begin to transform, the original object remains untouched, and a copy is transformed instead.
