It was the 'Apple' modifier and the bottom row, left to right... Z = Undo X = Cut C = Copy V = Paste 'twas always thus but Apple had some power to make it stick because of the single menu design and the Apple Uniform Interface Guidelines published very early on. Microsoft saw the wisdom of this and has implemented it across their applications. GUI applications tend to leverage this to provide for user familiarity. Obviously an application such as emacs which has roots which never anticipated a GUI interface doesn't conform to this familiarity. Craig
