Like the “adjust-tag” rule (see above,
the mark rule operates on an entry after scoring has completed. If
present, it simply specifies an integer; any entry whose score is
below this number will be marked as read (in that it will have the
'unread tag removed from it). Since bookmarked elfeed searches
typically specify the 'unread tag as a criterion, this
essentially means “if an entry’s score is below this number, don’t
even show it to me.”
Unlike the other rules, there may only be one mark rule.
Example:
(mark -2500)
