Is it done automatically ? Or do I need to do something special
in order to unset the unread tag ?

I see there is 'a' and 'x' when in notmuch-show but I am not sure
I have to explicitely press on of these keys.

Currently, when in a notmuch-search buffer, I press RET to visit
the thread and then I play with 'n' to go next message till I
read the whole thread. Then, I press 'q' to go back to the
notmuch-search buffer. Is this the way to do ?

Thank you
