How to do a "print screen" with a MacBook/MacBook Pro on the Windows side Since the MacBook/MacBook Pro don't have a "print screen" key you should try this:

  On the Windows side:

Shift + Fn + F11 (If your functions key controls the hardware)
Shift + F11 (If  your function keys behaves as normal  functions keys)

If you want take a screenshot of the active window jus add the Alt key.

Alt + Shift + Fn + F11 (If your functions key controls the hardware)
Alt + Shift + F11 (If  your function keys behaves as normal  functions keys)

Or if you use Mac OS:

command+shift+3 

or 

Command-shift-4 lets you select what portion of the screen to capture.

Note that either keystroke (-3 and -4) creates an image file that is, by default, a .png file saved to your desktop as "Picture 1" (2, 3, 4 and so on, however many you take).
