;;; Commentary:

;;   This package should, *theoretically*, serve to quieten the DEL/BS rwars
;;     a little.  By using this package, you can have DEL and BS both do the
;;     same function (normally delete one char to the left) or you can have
;;     then bound separately (DEL --> delete-char, BS --> delete-backward-char)
;;     with all appropriate Meta bindings in each mode.

(defun delbs-enable-delete-forward ()

  (define-key key-translation-map [delete] "\C-d")
  (define-key key-translation-map [(meta backspace)] "\M-\C-?")
  (define-key key-translation-map [(meta delete)] "\M-d"))
  
(defun delbs-disable-delete-forward ()
  "Return the DEL/BS key mappings to the XEmacs default"
