Re: customizing key definitions with Customize

[Richard M Stallman]

    Another alternative is to make keybindings first-class entities
    for Customize like faces with their `defface' definition.
    So customized and saved settings in a customization file
    would be like:

    (custom-set-keybindings
      ;; custom-set-keybindings was added by Custom.
      ;; If you edit it by hand, you could mess it up, so be careful.
      ;; Your init file should contain only one such instance.
      ;; If there is more than one, they won't work right.
     '(emacs-lisp-mode-map (([tab] 'lisp-indent-or-complete) ...))
     ...)

That looks clean and useful to me.
