Have you ever struggled with getting a selection just right? Maybe it was the wrong size or position. Or maybe you wish you could even rotate it after the fact? Good news: you can! This can be done by transforming the selection. Choose Select>Transform Selection, and now you can scale, rotate, and transform the selection in the same way that you would any object. Hold down the Shift key to constrain the proportions, and the Option (PC: Alt) key to transform from the center.
