[O] Adding user-defined task state for agenda

[Peter Davis]

I'm trying to add a NOTE state so that I can use agenda to quickly view a list 
of notes that I've embedded in various documents. I
have

(setq org-todo-keywords
      '((sequence "NOTE" "APPT" "TODO" "FEEDBACK" "VERIFY" "|" "DONE" 
"DELEGATED" "CANCELLED")))

in my .emacs, and I put

** NOTE This is an example of a note.

But when I view the agenda, I get this:

Global list of TODO items of type: NOTE
Available with `N r': (0)[ALL] (1)TODO (2)DONE (3)NOTE (4)APPT (5)CANCELLED 
(6)FEEDBACK (7)VERIFY (8)DELEGATED

and that's all. I can see that there's a NOTE state, but nothing shows up in 
the list.

Have I overlooked something?

Thank you!
