Yes, under some setups, circumstances, you have to do emit "C-x
o" to switch to the help buffer as well.  My finger do this so
quickly automatically that my brain hardly ever notices it anymore :-)

so this is a bug somewhere already.
I wonder why "n" and "p" work, but "s" (prefix for *s*kipping to sections)
fails. 

o What does 'C-h v  major-mode <Enter>' give inside the *help[R](lm)* buffer?
  It should give a *Help* buffer with something like

  major-mode's value is ess-help-mode
  Local in buffer *help[R](lm)*; global value is text-mode



o What does 's C-h' give  {inside the *help[R](lm)* buffer} ?
  It should give an *Help* buffer containing something like

    Major Mode Bindings Starting With s:
    key             binding
    ---             -------

    s <		beginning-of-buffer
    s >		end-of-buffer
    s ?		ess-describe-sec-map
    s v		ess-skip-to-help-section
    s u		ess-skip-to-help-section
    s s		ess-skip-to-help-section
    s r		ess-skip-to-help-section
    s n		ess-skip-to-help-section
    s e		ess-skip-to-help-section
    s D		ess-skip-to-help-section
    s d		ess-skip-to-help-section
    s a		ess-skip-to-help-section

  (I haven't yet take the time to analyze them ..)
