Due to this "ground-rule", almost no one has the F-keys bound to 
anything, except F1 (and sometimes F2 I think).  That's why ESS[SAS] 
gives you the option to use F2-F12.  In this case, the same
functionality that you would get from the SAS Display Manager with
some bells and whistles thrown in.  So, your fingers don't have to
learn new keys.  Enjoy!
