I didn't ask "what" the something is.  I asked "how" you want to
communicate that something to the tab.

I meant that this is the standard behavior associated with tabs: Display
something like a file or a webpage in the display area associated with
the tab.

But what do you want to do?  I suppose you want to show the tab that was
hidden before.  OTOH "show" in your nomenclature meant something
different so far: Do some standard action associated with the tab like
switching buffers or restoring a window configuration.

I referred to the window configuration example because so far that was
the only one where I "insisted" on providing a menubar entry rather than
a tab.  You can't accuse me of insistence with an example you didn't
provide before.  My argument was that the "'close event" for the *grep*
buffer is rather similar to a toolbar button provided by an email
problem which, when hit, causes the currently written mail to get sent
and the associated display area where that mail was shown removed.  I
don't know of any MUA that uses tabs for such a purpose but I don't want
to exclude it.

I also agree that the hourglass functionality of a tab you cited earlier
(that is changing the color of a tab while work like grep searching is
in progress) can be useful, for example, when performing a couple of
grep searches or compilations simultaneously.
