  27 ;; Org-mouse provides mouse support for org-mode.
  28 ;;
  29 ;; http://orgmode.org
  30 ;;
  31 ;; Org-mouse implements the following features:
  32 ;; * following links with the left mouse button (in Emacs 22)
  33 ;; * subtree expansion/collapse (org-cycle) with the left mouse button
  34 ;; * several context menus on the right mouse button:
  35 ;;    + general text
  36 ;;    + headlines
  37 ;;    + timestamps
  38 ;;    + priorities
  39 ;;    + links
  40 ;;    + tags
  41 ;; * promoting/demoting/moving subtrees with mouse-3
  42 ;;    + if the drag starts and ends in the same line then promote/demote
  43 ;;    + otherwise move the subtree
  44 ;;
  45 ;; Use
  46 ;; ---
  47 ;;
  48 ;; To use this package, put the following line in your .emacs:

  53 ;; FIXME:
  54 ;; + deal with folding / unfolding issues
  55
  56 ;; TODO (This list is only theoretical, if you'd like to have some
  57 ;; feature implemented or a bug fix please send me an email, even if
  58 ;; something similar appears in the list below.  This will help me get
  59 ;; the priorities right.):
  60 ;;
  61 ;; + org-store-link, insert link
  62 ;; + org tables
  63 ;; + occur with the current word/tag (same menu item)
  64 ;; + ctrl-c ctrl-c, for example, renumber the current list
  65 ;; + internal links
