The Warp command lets you drag control points to manipulate the shape of images, shapes, or paths, and so on. You can also warp using a shape in the Warp Style pop‑up menu in the options bar. Shapes in the Warp Style pop‑up menu are also malleable; drag their control points.
When using the control points to distort an item, choosing View > Extras shows or hides the warp mesh and control points.
