Thank you for your help. That works to get me started.

Now to return your favour:

Replace
       type= "FOUR_LEVEL",
       symbols[Group1]= [       Right,       Right,       Tab,       Tab ]
with
       type= "PC_FN_LEVEL2",
       symbols[Group1]= [       Right,       Tab ]

and you will retain the ability to highlight text with shift-right arrow.
