1. The problem is to understand the function of the 'Print Screen' (PrtSc) button on a keyboard. 2. The 'Print Screen' button is used to capture the current screen display as an image. 3. When you press the 'Print Screen' button, it copies the entire screen's content to the clipboard. 4. You can then paste this captured image into an image editor, document, or email by using the paste command (Ctrl+V). 5. This function is useful for saving or sharing exactly what is shown on your screen at that moment. 6. Note that pressing 'Print Screen' alone captures the whole screen, while pressing 'Alt + Print Screen' captures only the active window.
