  29 ;; Org-mouse provides mouse support for org-mode.
  30 ;;
  31 ;; http://orgmode.org
  32 ;;
  33 ;; Org-mouse implements the following features:
  34 ;; * following links with the left mouse button (in Emacs 22)
  35 ;; * subtree expansion/collapse (org-cycle) with the left mouse button
  36 ;; * several context menus on the right mouse button:
  37 ;;    + general text
  38 ;;    + headlines
  39 ;;    + timestamps
  40 ;;    + priorities
  41 ;;    + links
  42 ;;    + tags
  43 ;; * promoting/demoting/moving subtrees with mouse-3
  44 ;;    + if the drag starts and ends in the same line then promote/demote
  45 ;;    + otherwise move the subtree
  46 ;;
  47 ;; Use
  48 ;; ---
  49 ;;
  50 ;; To use this package, put the following line in your .emacs:
  51 ;;
  52 ;;    (require 'org-mouse)
  53 ;;
  54
  55 ;; Fixme:
  56 ;; + deal with folding / unfolding issues
  57
  58 ;; TODO (This list is only theoretical, if you'd like to have some
  59 ;; feature implemented or a bug fix please send me an email, even if
  60 ;; something similar appears in the list below.  This will help me get
  61 ;; the priorities right.):
  62 ;;
  63 ;; + org-store-link, insert link
  64 ;; + org tables
  65 ;; + occur with the current word/tag (same menu item)
  66 ;; + ctrl-c ctrl-c, for example, renumber the current list
  67 ;; + internal links
  68
  69 ;; Please email the maintainer with new feature suggestions / bugs
