Hi, Lisa here and I'm going to show you how to take a screen shot on your Mac. So once you find a screen that you want to take a screen shot of you are going to hold down shift, command, and the number 3. So you just go 1, 2, 3 and then it takes a screen shot of the entire screen.
So if we go to the file up here where it places it on the desktop you can open it and you'll see that we have the whole screen there. Now sometimes you just want a portion of the screen so to do that you'll go shift, command, and the number 4. So the same way as before shift, command, 4, and now you have a little cross hairs on your screen. So I just want the frog in the middle, so I'm going to draw a box around him and when I let go it takes the picture of that part so now when I open that file I see just the picture of the frog there. So there you go, that's how you take a screen shot on your Mac.
