- ;;; Commentary:
-
- ;; This package provides various useful commands (including help
- ;; system access) through the mouse. All this code assumes that mouse
- ;; interpretation has been abstracted into Emacs input events.
- ;;
- ;; The code is rather X-dependent.
-
- ;;; Code:
-
- ;;; Utility functions.
-
- ;;; Indent track-mouse like progn.
