There are two ways to do this, and they are functions of the Apple OS. Both of them are techniques for taking "Screen Shots"

1. HOLD [SHIFT] & [COMMAND] (the apple key), then press the number [3]. You'll hear a "camera shutter" sound. A picture of the ENTIRE screen has been taken, named "Picture 1", and place on you Mac HD.

2. HOLD [SHIFT] & [COMMAND] (the apple key), then press the number [4]. This time your mouse pointer will turn into crosshairs, which look like [ + ]. Simply click and drag the crosshairs across the area you want a snapshot of. When you release the mouse, you'll hear the "camera shutter" sound. A picture of your selection has been taken, named "Picture 2", and place on you Mac HD.

3. You can open your new picture files by simply double-clicking them in the Mac HD. They will opened by SimpleText, and you and choose PRINT from the FILE
