[ic] Hacking the Admin UI: tab highlights?

[Jeff Boes]

I need information on how the Admin UI sets up the tab highlighting in
the various levels of menu structure. For instance, in a particular
third-level menu page, when the user clicks a link they will be taken to
another non-sibling third-level menu, and I want to set up the
highlights for the superior menu tabs to make it look just as though the
user had navigated down into that non-sibling menu rather than "jumped
across".

I think the top-level one is controlled by a scratch variable,
"ui_class". But I haven't been able to tease out the details for the
second- and third-level settings.
