Thanks - sounds possible? But if I just use ,---- | :post (org-time-stamp-inactive) `---- 1) an input is required and 2) the time stamp is inserted before the #+begin_src and makes the block invalid. How can I put the time stamp in the line after the #+end_src or possibly even in the same line, as this does not seem to have an impact on the source block? Thanks, Rainer -- Rainer M.
