Thanks Alan and Marco!  You're replies were a big
help.  It seems that c-indent-line-or-region is the
function I need.  It turns out that on my system it's
not bound to any key by default.  So, I'm going to
bind it in my .emacs file but as I'm quite new to
EMACS I have a further question.  Is there some way to
get a list of currently unused key-combinations?  In
other words, how do I know what is a good key choice
to bind to?
