ENTER↑ is a misnomer, long live ENTER:

I respectfully plea for the right to disagree. ENTER↑ is a name fitting the classic RPN function well (compare e.g. R↓ and R↑, and look at all the pocket calculators from the HP-35 to the HP-41CX). Then the arrow was dropped since it didn't fit the Voyager keyboard; and it didn't return with the Pioneers for whatever reason. The real problem, however, arose with RPL (ab)using the RPN label ENTER for a slightly different function. IMHO it's the duty of the abuser to refrain from abuse - not of classic RPN to make way for it.

Luckily noone ever used ENTER↑ on an RPL or so-called 'Entry RPN' calculator. Thus I think ENTER↑ is perfectly correct on the WP 34S, while ENTER should be replaced by something else on the HP-30b. I doubt, however, that we'll get that - so returning to ENTER↑ on the WP 34S, 31S, and 43S is the minimum differentiation we can do to make people aware of what we're talking about.
