Snip & Sketch is a built-in application in Windows 10 and later versions that allows users to capture screenshots easily. It provides various tools for taking screenshots, including rectangular, freeform, window, and full-screen snips. After capturing an image, users can annotate it with a pen, highlighter, or text, making it useful for sharing information or providing feedback. The app can be accessed quickly using the keyboard shortcut Windows key + Shift + S, which opens a small menu for selecting the type of snip. Captured images can be saved, copied to the clipboard, or shared directly from the app, enhancing productivity and communication.
