Please help - I am aware of two different versions of the HP 12C Platinum financial calculator: some versions have the "minus" and "divide" keys imprinted with a blue ("G" key) sub-function operation - each are printed with differnet blue arrows on these minus and divide keys - while other 12C Platiunums do not have the printed function. Can anyone explain why? Thank you! Laskody
