I tested the code below, presented by John Fultz, but I have noticed
that, by using Tab, it is only possible to cycle through the
InputFields, but never set focus on the buttons. I did not find a
Panel option about this, either.
Do you know if is it possible to explicitely set the tab-accessible
components and also specify the "tabbing" order?

Thanks

ADL
