Re: PSGML mode should not override 'M-BS'.

DH> In my opinion, this is pretty counter-intuitive (i.e. a bug) in DH> xemacs. But Emacs would do the same if it also mapped C-h to Backspace instead of DEL. E.g. (progn (setq foo-map (make-keymap)) (define-key foo-map "\e\C-i" 'foo) (use-local-map foo-map)) Makes both keystrokes Meta+Control+i and Meta+Tab invoke foo in Emacs. Perhaps you are arguing that C-h should not be mapped to Backspace. I might even agree with that. But that will open several old cans of worms. Martin
