gnus: Setting Process Marks

 
 3.7.6 Setting Process Marks
 ---------------------------
 
 Process marks are displayed as ‘#’ in the summary buffer, and are used
 for marking articles in such a way that other commands will process
 these articles.  For instance, if you process mark four articles and
 then use the ‘*’ command, Gnus will enter these four articles into the
 cache.  For more information, SeeProcess/Prefix.
 
 ‘M P p’
 ‘#’
      Mark the current article with the process mark
      (‘gnus-summary-mark-as-processable’).
 
 ‘M P u’
 ‘M-#’
      Remove the process mark, if any, from the current article
      (‘gnus-summary-unmark-as-processable’).
 
 ‘M P U’
      Remove the process mark from all articles
      (‘gnus-summary-unmark-all-processable’).
 
 ‘M P i’
      Invert the list of process marked articles
      (‘gnus-uu-invert-processable’).
 
 ‘M P R’
      Mark articles that have a ‘Subject’ header that matches a regular
      expression (‘gnus-uu-mark-by-regexp’).
 
 ‘M P G’
      Unmark articles that have a ‘Subject’ header that matches a regular
      expression (‘gnus-uu-unmark-by-regexp’).
 
 ‘M P r’
      Mark articles in region (‘gnus-uu-mark-region’).
 
 ‘M P g’
      Unmark articles in region (‘gnus-uu-unmark-region’).
 
 ‘M P t’
      Mark all articles in the current (sub)thread
      (‘gnus-uu-mark-thread’).
 
 ‘M P T’
      Unmark all articles in the current (sub)thread
      (‘gnus-uu-unmark-thread’).
 
 ‘M P v’
      Mark all articles that have a score above the prefix argument
      (‘gnus-uu-mark-over’).
 
 ‘M P s’
      Mark all articles in the current series (‘gnus-uu-mark-series’).
 
 ‘M P S’
      Mark all series that have already had some articles marked
      (‘gnus-uu-mark-sparse’).
 
 ‘M P a’
      Mark all articles in series order (‘gnus-uu-mark-all’).
 
 ‘M P b’
      Mark all articles in the buffer in the order they appear
      (‘gnus-uu-mark-buffer’).
 
 ‘M P k’
      Push the current process mark set onto the stack and unmark all
      articles (‘gnus-summary-kill-process-mark’).
 
 ‘M P y’
      Pop the previous process mark set from the stack and restore it
      (‘gnus-summary-yank-process-mark’).
 
 ‘M P w’
      Push the current process mark set onto the stack
      (‘gnus-summary-save-process-mark’).
 
    Also see the ‘&’ command in SeeSearching for Articles, for how
 to set process marks based on article body contents.
