Hi MBR: To me, the search and replace syntax you're using is incorrect. Or perhaps \& is an undocumented feature -- you did mention that it sometimes works.
I would search for "\([A-Z]\)" and replace with "SPC\1".

M-< ;; Go to beginning of narrowed buffer M-x replace-regexp RET [A-Z] RET ;; Find any capital letter C-q SPC \& RET ;; Replace it with a space followed by itself M-< ;; Go to beginning of narrowed buffer C-d ;; Delete the unwanted space before the first letter So, if the narrowed portion of the buffer contains: "JohnJacobJingleheimerschmidt" after running this portion of the macro, it should contain: "John Jacob Jingleheimerschmidt" Instead, when run in Emacs 23, the result is: "ohnJacobJingleheimerschmidt" which is exactly what you'd expect if the M-x replace-regexp failed to do the replacement that it should have. -snip-
