    If you have multiple displays set up, this function will only grab the primary display; not all of them like you would with the 'Print Screen' key.

    Also, this should be pretty obvious but I'll mention it anyway, if you're running GPU-intensive applications (not CPU), calling this function will cause quite some significant lag to your machine and server response until the request is complete.
