Sorry, Juri.  Perhaps I read your email in a hurry. I'm not opposed to
having new forms of navigating history or other collections of potential
completions, of course.  I was just mentioning that within the current
completion interface, both the regular minibufer, Icomplete and Ido
have ways to reach back to history items using "reverse-isearch".  The
regular minibuffer's is triggered by C-r and in Ido it's simply a question
of typing something, then typing M-p, if I recall correctly.  In Icomplete,
C-r works , but what follows is not completely intuitive, IMO. It should
be perfected.  What I said for Icomplete goes for Fido, except that uses
C-M-r because its C-r is used for something else.
