Here's a very quick hack/proof of concept. There's very likely a better
way to do it. This is simply to illustrate the general idea.

--8<---------------cut here---------------start------------->8---
(defun my-org-next-next ()
  (interactive)
  (forward-word)
  (when (re-search-forward "\\*+\\s-+NEXT" nil t)
    (org-reveal t))
  (org-back-to-heading))

(add-to-list 'org-speed-commands-user '("N" . (org-speed-move-safe 'my-org-next-next)))
--8<---------------cut here---------------end--------------->8---

Best,
Matt
