When working with an object or shape on a layer, you can use Free Transform (Command-T [PC: Ctrl-T]) to rotate, scale, skew, and keep doing all sorts of stuff to it. Did you know you can also use a kind of free transform on selections? It’s called Transform Selection. Choose Select>Transform Selection, and you’ll see a bounding box around the selection, where you can change the shape, move it, rotate it, etc. This option is so useful, I assigned a keyboard shortcut to it (Edit>Keyboard Shortcuts). Ironically, I use Command-Y (PC: Ctrl-Y) from the previous tip, so I don’t accidentally turn on Proof Colors. There you go! Two tips for one.
