You would bind `th-gnus-summary-toggle-show/hide' to some key in
`gnus-summary-mode-map' just like you did with the other two commands.
This command is a combination of both: calling it on a collapsed thread
will expand it, calling it on a expanded thread collapses it again.

I have bound it to M-TAB like that

  (define-key gnus-summary-mode-map (kbd "<M-tab>")
              'th-gnus-summary-toggle-show/hide)

Simply TAB is not that good, because that's already used for jumping
between links...

Bye,
