How to refresh tag list in org-mode without closing and reopening emacs

Question

In my emacs org-mode org file I have a tag list

#+TAGS: OFFICE(o) COMPUTER(c) HOME(h) PROJECT READING(r) PHOTOGRAPHY(p)

At some point, I wish to add a new tag to the list, and apply it to an item (using C-c C-c). But the new tag does not show up in the list of selectable tags.

In order to fix this, I close and reopen emacs. But I'm sure that isn't necessary, How do I refresh this list without restarting emacs?

Answer 1

Try C-c C-c on the top of the org file. It updates the local config of the file.
