... Looking into the future it is important that the key has a name that speaks for itself. Imho ENTER: gives future users of Classical RPN a much better intuitive feeling for the semantic of this key in Classical RPN calculators than ENTER↑.

Sorry, I continue disagreeing. While ENTER: looks like a label to me (no operation), ENTER↑ describes what the operation does - it enters a number in the stack. Even the arrow points in the right direction (although HP talks about pushing values on the stack, it pushes them below the stack in reality - but that's another story). I'm pretty sure you'll also find ENTER↑ on the 43S.
