Thanks for that hint. Alas, I found a subtle difference there. Try the 
following:  Use

(define-key global-map [?\C-f] (lookup-key global-map [?\C-s]))

to set C-f and then open some local directory (Emacs showing "Dired by 
name"). There, type Control-f and some search key that can be found 
repeatedly in your directory. Then press Control-f repeatedly.  My 
observation is that repeated search by Control-f doesn't work like it 
does when you use Control-s directly. However, if you use remap C-f using

(define-key key-translation-map "\C-f" "\C-s")

then repeated searching works with Control-f. This observation was made 
on Emacs 23.3.1. Can you repeat this in your version of Emacs? Any ideas 
for explanation?
