But when 'navi-search-and-switch' would have a bug, one could not use
navi-mode at all ... and I use it all the time.

looks good so far.

1. Can you try 'navi-search-and-switch' on an org-mode buffer, with ->
(eq major-mode 'org-mode), e.g.

,----
| * ORG SCRATCH
| ** 2nd Level
| #+BEGIN_SRC emacs-lisp :cache no
|  (+ 2 2)
| #+END_SRC
`----

*Navi* buffer should pop-up, typing 2 should show both headlines.

2. Is there anything special about the outshine file you used? Is it
structured with outshine headers? is it emacs-lisp-mode? old-school or
org-style headers?
