;;; Commentary:

;; This file is loaded by x-win.el at run-time when we are sure that XEmacs
;; is running on the display of a Sun.

;; The Sun X server (both the MIT and OpenWindows varieties) have extremely
;; stupid names for their keypad and function keys.  For example, the key
;; labeled 3 / PgDn, with R15 written on the front, is actually called F35.

;; There are 3 methods of dealing with the Sun key brokenness:
;;
;; - Use xmodmap to give all keys more sensible names for all apps:
;;   I use this shell script:
;;
;;   for i in 0 1 2 3 4 5 6 7 8 9 Add Subtract Multiply Divide Decimal ; do
;;     echo "keysym KP-$i = KP-$i"
;;   done | xmodmap
;;
;;   Clearly, as a good X11 citizen, we can't do this.
;;
;; - Use keyboard-translate-table to remap the keybindings at a low level.
;;   This approach is taken in the function `sun-x11-keyboard-translate'.
;;   This is like running xmodmap within XEmacs only.
;;   This is not the default, however, so that legacy keybindings in users'
;;   .emacs files like (global-set-key [(f35)] 'foo) continue to work
;;
;; - Use keyboard macros to provide indirection for keybindings.
;;   If we do (global-set-key [(f35)] [(kp-3)]), then the user's keybindings
;;   work whether he uses `f35' or `kp-3'.
;;   This is also compatible with FSF Emacs and other X11 apps.
;;   Although this has the disadvantage that these remappings
;;   only work with the global key map, we use this as the default.
;;
;; - The Right Way to do this remains to be written...

;; OK, here's another try at doing things the right way.

;; We use function-key-map, which honors explicit key-bindings for the
;; stupid Sun names, but also allows indirection if no explicit
;; key-binding exists.
