+;; Functions for manipulating via the mouse and mouse-map definitions
+;; for accessing them.  Also definitions of mouse menus.
+;; This file you should freely modify to reflect you personal tastes.
+;;
+;; First half of file defines functions to implement mouse commands,
+;; Don't delete any of those, just add what ever else you need.
+;; Second half of file defines mouse bindings, do whatever you want there.
+
+;;
+;;         Mouse Functions.
+;;
+;; These functions follow the sun-mouse-handler convention of being called
+;; with three arguments: (window x-pos y-pos)
+;; This makes it easy for a mouse executed command to know where the mouse is.
+;; Use the macro "eval-in-window" to execute a function 
+;; in a temporarily selected window.
+;;
+;; If you have a function that must be called with other arguments
+;; bind the mouse button to an s-exp that contains the necessary parameters.
+;; See "minibuffer" bindings for examples.
