gnus: Searching for Articles

 
 3.27.2 Searching for Articles
 -----------------------------
 
 ‘M-s’
      Search through all subsequent (raw) articles for a regexp
      (‘gnus-summary-search-article-forward’).
 
 ‘M-r’
      Search through all previous (raw) articles for a regexp
      (‘gnus-summary-search-article-backward’).
 
 ‘M-S’
      Repeat the previous search forwards
      (‘gnus-summary-repeat-search-article-forward’).
 
 ‘M-R’
      Repeat the previous search backwards
      (‘gnus-summary-repeat-search-article-backward’).
 
 ‘&’
      This command will prompt you for a header, a regular expression to
      match on this field, and a command to be executed if the match is
      made (‘gnus-summary-execute-command’).  If the header is an empty
      string, the match is done on the entire article.  If given a
      prefix, search backward instead.
 
      For instance, ‘& RET some.*string RET #’ will put the process mark
      on all articles that have heads or bodies that match
      ‘some.*string’.
 
 ‘M-&’
      Perform any operation on all articles that have been marked with
      the process mark (‘gnus-summary-universal-argument’).
