gnus: Limiting

 
 3.8 Limiting
 ============
 
 It can be convenient to limit the summary buffer to just show some
 subset of the articles currently in the group.  The effect most limit
 commands have is to remove a few (or many) articles from the summary
 buffer.
 
    Limiting commands work on subsets of the articles already fetched
 from the servers.  These commands don’t query the server for additional
 articles.
 
 ‘/ /’
 ‘/ s’
      Limit the summary buffer to articles that match some subject
      (‘gnus-summary-limit-to-subject’).  If given a prefix, exclude
      matching articles.
 
 ‘/ a’
      Limit the summary buffer to articles that match some author
      (‘gnus-summary-limit-to-author’).  If given a prefix, exclude
      matching articles.
 
 ‘/ R’
      Limit the summary buffer to articles that match some recipient
      (‘gnus-summary-limit-to-recipient’).  If given a prefix, exclude
      matching articles.
 
 ‘/ A’
      Limit the summary buffer to articles in which contents of From, To
      or Cc header match a given address
      (‘gnus-summary-limit-to-address’).  If given a prefix, exclude
      matching articles.
 
 ‘/ S’
      Limit the summary buffer to articles that aren’t part of any
      displayed threads (‘gnus-summary-limit-to-singletons’).  If given a
      prefix, limit to articles that are part of displayed threads.
 
 ‘/ x’
      Limit the summary buffer to articles that match one of the “extra”
      headers (SeeTo From Newsgroups)
      (‘gnus-summary-limit-to-extra’).  If given a prefix, exclude
      matching articles.
 
 ‘/ u’
 ‘x’
      Limit the summary buffer to articles not marked as read
      (‘gnus-summary-limit-to-unread’).  If given a prefix, limit the
      buffer to articles strictly unread.  This means that ticked and
      dormant articles will also be excluded.
 
 ‘/ m’
      Ask for a mark and then limit to all articles that have been marked
      with that mark (‘gnus-summary-limit-to-marks’).
 
 ‘/ t’
      Ask for a number and then limit the summary buffer to articles
      older than (or equal to) that number of days
      (‘gnus-summary-limit-to-age’).  If given a prefix, limit to
      articles younger than that number of days.
 
 ‘/ n’
      With prefix ‘n’, limit the summary buffer to the next ‘n’ articles.
      If not given a prefix, use the process marked articles instead.
      (‘gnus-summary-limit-to-articles’).
 
 ‘/ w’
      Pop the previous limit off the stack and restore it
      (‘gnus-summary-pop-limit’).  If given a prefix, pop all limits off
      the stack.
 
 ‘/ .’
      Limit the summary buffer to the unseen articles
      (‘gnus-summary-limit-to-unseen’).
 
 ‘/ v’
      Limit the summary buffer to articles that have a score at or above
      some score (‘gnus-summary-limit-to-score’).
 
 ‘/ p’
      Limit the summary buffer to articles that satisfy the ‘display’
      group parameter predicate
      (‘gnus-summary-limit-to-display-predicate’).  SeeGroup
      Parameters, for more on this predicate.
 
 ‘/ r’
      Limit the summary buffer to replied articles
      (‘gnus-summary-limit-to-replied’).  If given a prefix, exclude
      replied articles.
 
 ‘/ E’
 ‘M S’
      Include all expunged articles in the limit
      (‘gnus-summary-limit-include-expunged’).
 
 ‘/ D’
      Include all dormant articles in the limit
      (‘gnus-summary-limit-include-dormant’).
 
 ‘/ *’
      Include all cached articles in the limit
      (‘gnus-summary-limit-include-cached’).
 
 ‘/ d’
      Exclude all dormant articles from the limit
      (‘gnus-summary-limit-exclude-dormant’).
 
 ‘/ M’
      Exclude all marked articles (‘gnus-summary-limit-exclude-marks’).
 
 ‘/ T’
      Include all the articles in the current thread in the limit.
 
 ‘/ c’
      Exclude all dormant articles that have no children from the limit
      (‘gnus-summary-limit-exclude-childless-dormant’).
 
 ‘/ C’
      Mark all excluded unread articles as read
      (‘gnus-summary-limit-mark-excluded-as-read’).  If given a prefix,
      also mark excluded ticked and dormant articles as read.
 
 ‘/ b’
      Limit the summary buffer to articles that have bodies that match a
      certain regexp (‘gnus-summary-limit-to-bodies’).  If given a
      prefix, reverse the limit.  This command is quite slow since it
      requires selecting each article to find the matches.
 
 ‘/ h’
      Like the previous command, only limit to headers instead
      (‘gnus-summary-limit-to-headers’).
 
    The following commands aren’t limiting commands, but use the ‘/’
 prefix as well.
 
 ‘/ N’
      Insert all new articles in the summary buffer.  It scans for new
      emails if BACK-END‘-get-new-mail’ is non-‘nil’.
 
 ‘/ o’
      Insert all old articles in the summary buffer.  If given a numbered
      prefix, fetch this number of articles.
