This may not work in your .emacs, as pov-mode is not started when emacs 
is launched. You should probably do it as a lambda function on the right 
hook

(pov-mode-hook (quote (lambda nil
    (define-key pov-mode-map [(control c) (control i)] (quote 
pov-complete-word)))))

No work to be done : there's a function caled dabbrev which 
automatically completes with the word which have previously been typed 
in your buffer

(global-set-key [(f8)] 'dabbrev-completion)

For more information and knowing the difference between dabbrev-expand 
and dabbrev-completion (not exactly the same behaviour), use C-h a 
dabbrev [return]
(C-h => help, a => regexp search)
Note : this is bundled in my xemacs installation, but I think I had to 
install it on fsf emacs. Some google(ing will probably tell you where 
you can find it

Emacs has so many packages that almost everuthing is possible without 
any lisp hacking (except for configuration purposes, but can we REALLY 
name it hacking?)

Enjoy and have fun!
