If you’ve used Free Transform (Command-T [PC: Ctrl-T]) to scale down a layer, and want to apply the exact same transformation to a different layer, press Shift-Command-T (PC: Shift-Ctrl-T). That’s the shortcut for Transform Again, meaning repeat whatever you did: scale, rotate, move, or any combination of transformations. Bonus: If you want to apply the transformation to a copy, press Option-Shift-Command-T (PC: Alt-Shift-Ctrl-T).
