Of course, rms means "Richard M Stallman", too!

But as you noted, the manual is wrong.  I'm really surprised that such
an error has been around so long.  "A" should stand for "absolute
value", which for a vector should be the norm.
Offhand, I don't see the RMS function in Calc.  If it isn't there, I'll
(for now) remove that paragraph from the manual, and after the Emacs
feature freeze is over I'll put in the RMS function.  Then I'll put the
paragraph back in the manual, with the correct keybinding.
