    I have a bunch of key assignments that I make.
    To show them on the "keyboard" you can use a graphics program like Paint to add them to the relevant .bmp file in the program directory. There are three, small.bmp, medium.bmp and large.bmp . Remember to change the Properties on the Folder holding the program. Win7 has it as Read Only.

      According to
      http://www.greendyk.nl/hp41c-manual/index.php?p=84
      Press [XEQ] then followed by
      [ALPHA] [Gold Shift] [ % ] [ C ] [ H ] [ALPHA]
      For example to find the percentage difference between the value of 100 and 125.
      Type 100
      Press [Enter]
      Type 125
      Press [XEQ] then followed by
      [ALPHA] [Gold Shift] [ % ] [ C ] [ H ] [ALPHA]
      It should display the answer of
      25
