I'm having a problem snapping a picture of my screen, I read somewhere on this forum to take a picture of my screen press> Command+space+3 and the picture will be taken and saved to my desktop. I've done the above on Mavericks, and it looks like it's snapping a picture, but I can't find it anywhere. Also the spotlight pane opens up. am I doing something wrong? can someone please give me some advise how to set this up, and how to operate this feature.
