This describes a org-tag-alist for setting up globally a list of tags, but I'm not sure how to alter org-tag-alist. I'm used to doing an M-x customize-variable, but there is no org-tag-alist. Later on the page it has this form:
(setq org-tag-alist '(("@work" . ?w) ("@home" . ?h) ("laptop" . ?l)))
which seems to be something to put in my .emacs, i.e., org-tag-alist is not an existing variable?
