The original idea was both better > and simpler. Let me express more clear what I meant: not each command should test the flag, but only a new function `show-buffer' used by these commands. So for instance having (defun foo () (interactive) ... (show-buffer new-buffer)) bound to some key (e.g. `C-c C-f'). Then after typing `C-x 4 C-c C-f', the prefix `C-x 4' will set some special variable, and `show-buffer' called by this command will detect it and put `this-command' to the user config alist with a flag to reuse this user preference next time this command is called without the prefix `C-x 4'. > Another drawback of this method is you'd have to type C-x 4 C-x C-f. You have to type `C-x 4 C-x C-f' only once. After `show-buffer' records the fact of calling with the prefix `C-x 4' first time, it will reuse this preference on subsequent invocations without the prefix `C-x 4'. -- Juri Linkov http://www.jurta.org/emacs/
