There is one key on the keyboard that might seem a little odd: PrtScn. It’s not immediately obvious what this key does or why you would want to use it, but we assure you that it is an extremely helpful keyboard shortcut once you understand how it works and why you might want to try it out. In reality, the PrtScn key (on some keyboards it might just be PrtSc) is important for taking screenshots on your Windows device.
