how to find thread after jumping to article

[Peter Rooney]

hi all,

in the summary buffer, i used j (gnus-summary-goto-article) to
successfully jump to an article that was at least six months old (if
that's relevant).

i then wanted to read the thread descending from that article. neither
T s (gnus-summary-show-thread) nor TS
(gnus-summary-show-all-threads). i checked the manual for Threading and
the Summary Buffer but did not see the answer.

thanks in advance
peter
