Cut to the Quick on Screen Printing

On the Mac and keyboard: Hold down the Apple command key plus the shift key and press the numeral #4. After that you will get a marquie with cross hairs on it. Place the crosshair marquie and drag over the image. You will hear a faint click, like a camera shutter. The Image will be placed to your desktop as a PDF file in OSX 70DPI. And on the hard drive in OS9.

Hold down the Apple command key plus the shift key and press the numeral #3. That will get you a full screen shot that is saved to your hard drive. Usually listed as a Picture file and so forth.

That's how it's done on a Mac. May be more difficult on the PC with a Mac keyboard. Nice question!
Why would you use a Mac keyboard on a PC in the first place! Doesn't the PC have a pull-down menu to print the screen? Why use the keyboard at all?
