Did you mean -ticked or something else rather than -unread?

As a note I wouldnt put that fixed length empty string in - rather try
and use padding formatting in the format string if its possible.

> idea on how to do such?

It's a cross fingers and hope for the best when hacking gnus ;) I only
found that var by googling and staring at other similar examples. There
often seems no rhyme nor reason to what is available but there
invairably is ;) I asked a couple of times about how to determine what
is available but didn't get much success. Digging in the code is the
best advice I can give.


best of luck!
