	25	;; Org-mouse provides mouse support for org-mode.
	26	;;
	27	;; https://orgmode.org
	28	;;
	29	;; Org mouse implements the following features:
	30	;; * following links with the left mouse button
	31	;; * subtree expansion/collapse (org-cycle) with the left mouse button
	32	;; * several context menus on the right mouse button:
	33	;; + general text
	34	;; + headlines
	35	;; + timestamps
	36	;; + priorities
	37	;; + links
	38	;; + tags
	39	;; * promoting/demoting/moving subtrees with mouse-3
	40	;; + if the drag starts and ends in the same line then promote/demote
	41	;; + otherwise move the subtree
	42	;;
	43	;; Use
	44	;; ---
	45	;;

	52	;; + deal with folding / unfolding issues

	54	;; TODO (This list is only theoretical, if you'd like to have some
	55	;; feature implemented or a bug fix please send me an email, even if
	56	;; something similar appears in the list below. This will help me get
	57	;; the priorities right.):
	58	;;
	59	;; + org-store-link, insert link
