I wanted to set the keyboard shortcut for "Copy a screenshot of a window to clipboard" to Alt+Print but it wouldn't allow me. I could use other combinations however, Ctrl+print, Shift+Print, etc. I disabled the Alt key in Compiz to show the HUD as well so nothing happens when I tap or press Alt, but it still doesn't let me use it in the keyboard shortucts menu.
