double bucky
     
        Using both the CTRL and META keys.  "The command to burn all
        LEDs is double bucky F."
     
        This term originated on the Stanford extended-ASCII keyboard,
        and was later taken up by users of the {space-cadet keyboard}
        at MIT.  A typical MIT comment was that the Stanford {bucky
        bits} (control and meta shifting keys) were nice, but there
        weren't enough of them; you could type only 512 different
        characters on a Stanford keyboard.  An obvious way to address
        this was simply to add more shifting keys, and this was
        eventually done; but a keyboard with that many shifting keys
        is hard on touch-typists, who don't like to move their hands
        away from the home position on the keyboard.  It was
        half-seriously suggested that the extra shifting keys be
        implemented as pedals; typing on such a keyboard would be very
        much like playing a full pipe organ.  This idea is mentioned
        in a parody of a very fine song by Jeffrey Moss called "Rubber
        Duckie", which was published in "The Sesame Street Songbook"
        (Simon and Schuster 1971, ISBN 0-671-21036-X).  These lyrics
        were written on May 27, 1978, in celebration of the Stanford
        keyboard:
     
                          Double Bucky
     
          Double bucky, you're the one!
          You make my keyboard lots of fun.
              Double bucky, an additional bit or two:
          (Vo-vo-de-o!)
          Control and meta, side by side,
          Augmented ASCII, nine bits wide!
              Double bucky!  Half a thousand glyphs, plus a few!
                  Oh,
                  I sure wish that I
                  Had a couple of
                      Bits more!
                  Perhaps a
                  Set of pedals to
                  Make the number of
                      Bits four:
                  Double double bucky!
          Double bucky, left and right
          OR'd together, outta sight!
              Double bucky, I'd like a whole word of
              Double bucky, I'm happy I heard of
              Double bucky, I'd like a whole word of you!
