setting new shortcut for tag search on emacs org-mode

Question

This is probably simple, but I've been trying it for a couple days now without success. I have a tag called :urgent:, which I can access through:

C-c / m urgent

Question is, how can I create a shortcut to get it done with, say, f9?

Answer 1

(defun hello-world ()
"My doc-string."
(interactive)
  (org-tags-view nil "urgent"))

(global-set-key [f9] 'hello-world)
;; or, use the following form instead of the one immediately above:
;; (define-key global-map [f9] 'hello-world)
