- ;;; Functions for manipulating via the mouse and mouse-map definitions
- ;;; for accessing them. Also definitons 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 arguements: (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.

- ;;; Global Mouse Bindings.
- ;;;
- ;;; There is some sense to this mouse binding madness:
- ;;; LEFT and RIGHT scrolls are inverses.
- ;;; SHIFT makes an opposite meaning in the scroll bar.
- ;;; SHIFT is an alternative to DOUBLE (but double chords do not exist).
- ;;; META makes the scrollbar functions work in the text region.
- ;;; MIDDLE operates the mark
- ;;; LEFT operates at point
-
- ;;; META commands are generally non-destructive,
- ;;; SHIFT is a little more dangerous.
- ;;; CONTROL is for the really complicated ones.
-
- ;;; CONTROL-META-SHIFT-RIGHT gives help on that region.
