To screenshot on a computer (Windows PC), there are several common methods:

• Press Windows key + Shift + S to open the snipping tool overlay where you can select a portion of the screen to capture. The screenshot is copied to the clipboard for pasting or editing.

• Press the Print Screen (PrtSc) key to capture the entire screen and copy it to clipboard, then paste it into an image editor or document.

• Press Windows key + Print Screen to capture the entire screen and automatically save the image to the "Screenshots" folder in "Pictures".

• Press Alt + Print Screen to capture only the currently active window and copy to clipboard for pasting.

• Use the Snipping Tool app by opening it from the Start menu for various screenshot modes like rectangular, freeform, window, and full screen, and options to annotate and save images.

These methods work out-of-the-box on Windows computers and cover capturing the full screen, an active window, or a custom area with easy saving and editing options. If a Mac computer method is needed, that can be provided as well.
