Problems binding keys

[Dan Anderson]

I'm trying to figure  out how to bind some keys and  place the LISP in
my .emacs.  I  can't figure out how to use  the "vectors" to represent
keys.  For instance, I think the following should work:

(global-set-key "C-c f" font-lock-mode)

But I just get a bunch of lisp errors. 

What am I doing wrong?

Thanks,

Dan
