      This mapping depends on the used OS and keyboard layout.
  
      .. warning :: This method is currently only a dummy that always
         returns the same mapping from characters to keys. It works fine
         on my Linux and Windows 7 machine using English/US keyboard
         layouts, but other layouts will eventually have to be
         supported.
