Thank you for the information!

remapped the ac-expand now. There is just one more annoyance: When the 
completions popup-menu gets displayed, for every line that has an org-style 
*heading, the completions line drawn over it starts just with the first letter 
and then an ellipsis "..."

I try to present an org snippet for an example:

#+BEGIN_org-sample
* first heading
--- popup-menu starts here ---
cobra
c...
c...
c...
c...
computer
connection
--- popup menu ends here ---
co<point>

some more text
#+END_org-sample

All lines in the popup menu that start with c..., would be real completion 
candidates, which get folded away because of underlying folded org-headings.

Any ideas on this?
