Calling [On]+[+] and [On]+[-] "hidden" is a stretch, since they are fully explained exactly where they should be:

(1) Quick Start Guide, page 10 (English edition)
(2) User Guide, page 4 (English edition)
(3) The online Help system, in the entry for the On key, which also explains 4 other On-key combinations.

HOWEVER, it would be interesting and useful to have a list of all the as-yet undocumented RPL commands, Prime keystroke functionalities, and any other "secret" features.
