arrow keys work fine for me (and also for Bernt Hansen, as he says in
another message).  What are your arrow keys bound to?  Try "C-c h"
followed by an arrow key (say down) to see what command will be
invoked.  In my case, it is

<down> runs the command org-agenda-next-line

which is the same command that will be invoked if you hit "n".
