When you press the PrtScn button, it saves the shot to the clipboard for you to paste into another application with Ctrl + V. However, with the Screenshoter software we can take snapshots and save them to a specified folder with the PrtScn key so there’s no requirement to paste them into an application. With this program you can also take shots of selected areas.
