So it seems like window-system is > a powerful tool for obfuscating Lisp code. That's true and I generally completely agree that it's not the right tool, but in the present case, the user wants the behavior to depend on the kind of window system in use, really and the `window-system' variable is the best there is for this right now. And the only problem I can think of with that variable is "what happens if the running Emacs has some frames open in X others in Gtk others in a tty and yet others in carbon" ? Of course, this can't happen right now, so it's not a problem yet. The only reason to deprecate the use of window-system is because it's generally misused. And realistically, it's not going to go away any time soon, even if it's deprecated because many many many people use it. So we should just live with it. If people misuse it, let's educate them. The same problem appears with (string-match "Lucid\\|XEmacs" emacs-version), yet we're not deprecating string-match, are we ? Stefan
