Org Agenda seems not to respect lines beginning with ":" or other literal examples.
E.g., adding a line like this will populate the Org Agenda: : (<%%(diary-float t 3 -1)> in org-mode) Similarly for: #+begin_src org (<%%(diary-float t 3 -1)> in org-mode) #+end_src #+begin_src emacs-lisp ;; (<%%(diary-float t 3 -1)> in org-mode) #+end_src #+begin_src (<%%(diary-float t 3 -1)> in org-mode) #+end_src AN EXCEPTION TO THE ABOVE This information only shows up in the agenda if it falls below a heading in the file, e.g., * Hello : (<%%(diary-float t 3 -1)> in org-mode) #+begin_src org (<%%(diary-float t 3 -1)> in org-mode) #+end_src #+begin_src emacs-lisp ;; (<%%(diary-float t 3 -1)> in org-mode) #+end_src #+begin_src (<%%(diary-float t 3 -1)> in org-mode) #+end_src Without the heading "* Hello", the data does *not* flow into the agenda. -- Dr Joseph A.
