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