Since there does not appear to be such a feature, a simple fix is to reload init.el, or if testing, evaluate a temporary modification in scratch buffer and run the following function which I have in my "general library" (defun reload-buffer ()   "Reload the current buffer"   (interactive)   (let ((curfile (buffer-file-name)))     (kill-this-buffer) (find-file curfile))) Which has a key binding, so all buffers can be updated fairly quickly. Not to add to Emanuel's protestations, but the 'desktop package has the same issues. Oh, well, case closed ... -- Tim tj49.com
