Here's some doc from trn, uppercaseified by me,
plus my own hint or two (hint to me):
:cmd ** Perform a command on ALL the SELECTED articles (use :p to post).
::cmd Perform a command on ALL NON-selected articles.
:.cmd **** Perform a command on THE current THREAD or its selected articles.
::.cmd ****** Perform a command on the UNselected articles IN the current THREAD.
****** (INCLUDING, in the show-via-t-cmd tree, PAREN-WRAPPED-articles)
[NOTE: to mark thread "NOT YET READ", use TWO-colons-dot: ::.m]
(ignore the asterisks, means importance to me)
Say I'm in a thread, everything marked "read already",
and that's due to my mistake -- I now want to
get them all marked UN-read.
Reading the above (not including my two hint-lines, lines 5 & 6),
it's seem you'd use ":.", ie ":.m".
But that seems to have no effect at all.
However, TWO-colons-dot *does* work, eg: "::.m".
Suggestion: haave the two-colon-dot doc change "unselected"
to "unselected or already-read".
Or am I confused?
(for what I wanted to do, mark all read articles in the current
thread as unread, ::.m *is* the correct thing to do? (worked
for me.) Any other (preferable) way?)
