X [ENTER] Y [MTH] [REAL] and now you have all % related commands available after two easy to remember keystrokes.
(I personally would do: X [SPC] Y [MTH] [REAL] and then %whatever...)

BTW on HP50 prof. Rautenberg's KEYMAN would let you assign REAL menu as a 'longhold' of MTH key in case you use it often.

Thanks, but the point of the DUP (or double ENTER) was to preserve the first number entered, as occurs on RPN calculators like the 15C, 42S, etc. That was the main point of my question. However, ANS/LASTARG is better still, in some cases.

I've been meaning to look into KEYMAN, thanks for the reminder.
