On my mac my keyboard has an eject button right next to f12(volume up). If I press that then the primary disk drive ejects its disk.

If I had two disk drives, I'm not sure which it would eject. I suspect that this is what WayneDB was referring to.

To chime in on the screenshot issue - the only real way around a shortcut is to have some sort of Window... And you'd have to have some sort of setting that hides the window. I think Gnome has something like that.
