I just learned a cool new keyboard shortcut from a friend of mine.
You probably know that you can press PrtSc (Print Screen) on your keyboard to take a screenshot, but did you know that if you press ctrl+alt+PrtSc it takes a screenshot of your active window. It comes in pretty handy.
Oh and by the way if you didn’t know that PrtSc takes a screenshot. You have to know that you first press PrtSc to take the screenshot and then you have to open a graphics editor (Gimp, Photoshop, Microsoft Paint). Then create a new image and press ctrl+v to paste it into the editor.
