The CUA bindings for Cut, Copy, Paste are actually Shift+Delete, Control+Insert, Shift+Insert. Microsoft adopted the X/C/V shortcuts from the Macintosh for Windows 3.0 (replacing Command by Control; Alt was already used for invoking menus and the like), in addition to the existing CUA shortcuts (which are still supported and used today).
