[O] Filtering Agenda View

[Ken Mankoff]

I'd like my agenda to not show waiting items. I'm not sure of the best
way to implement this, but my current solution has been:

                  (agenda "" (
                                          (org-agenda-overriding-header 
"Scheduled")
                                          (org-agenda-skip-function 
'(org-agenda-skip-entry-if 'regexp"WAITING"))
                                          ))


However, this is too restrictive (too loose a filter). It skips TODO
items that are in state TODO but have recorded, somewhere in their
body, the word WAITING such as

   - State "WAITING"    from "TODO"       [2012-09-03 Mon 11:45]

I tried setting the regexp to "\ WAITING\ " but that did not fix it.

How can I improve the regexp, or is there a better way to show TODO
items that are TODO, STARTED, WHATEVER, but not WAITING (or not
WAITING and SOMETHINGELSE).

Thanks,

  -k.
