I was unaware of them as well - I just quickly checked the docs when
you asked.  There might be a better way of doing it that I'm not aware
of.

I'm not entirely sure what you mean.  Are you trying to make the
taborder of a specific subset of the widgets in your window wrap
around, as opposed to continuing on to other widgets?  If so, I think
you might need to fiddle with the focus settings of the other widgets.
 As I said, I've never actually used these functions, so I'm not
certain.
