I suggest you look at

http://www.hpcalc.org/hp49/apps/editors/emacs211a.zip

Do a complete install with SDiag and extable on SD-card.
Then run AsnEmacs

Then you get an extended editor with description of USER-rpl (and all others commands as well) on the calculator.
I find it very helpful

Best regards
