Adobe is working on a new tool for Photoshop CC called the "Curvature Pen Tool," and earlier today the software maker released this sneak peek video to show you how it will work.

The tool—which will be added to "an upcoming release of Photoshop CC" according to Photoshop Product Manager Meredith Payne Stotzner—is very simple to use. It works by creating curved lines between points in your selection as you create a path. Each click adds a new point, clicking a point twice turns it into a sharp corner, and once your path is complete you can add, move and toggle points between rounded and sharp edges without ever changing to another tool.

Watch the sneak peek above to see how Stotzner uses the tool, first to create a custom shape, and then to create a perfect selection of a window frame.
