selecting tab button from script

[Mark Swindell]

What is the proper way to hilite/select a tabbed button from a script?  I
have two nearly identical navigation tabbed button sets on two different
groups, and when I jump groups it goes to the correct card but doesn't
hilite the proper tab upon getting there.

The "select menuItem x of menu 'buttonName'" doesn't seem to work," and I
can't locate the info in the docs.  Trying to figure out how tabbed buttons
and menus distinguish themselves.

Thanks
Mark
