Help for filter

Output may be filtered in the /review and /style commands based on the following
criteria:

  events:            See "/help events" for a list of event types.    
  ignored:           Events involving ignored users.                  
  unignored:         Events involving unignored users.                
  user users:        Events involving specific users.                 
  discussion discs:  Events involving specific discussions.           
  from users:        Messages sent by specific users.                 
  to targets:        Messages sent to specific targets.               
  match str:         Messages containing a specific string.           
  pmatch regexp:     Messages with text matching a regular expression.

Targets can be either users or discussions.

You may select multiple events, users, or targets with a comma-separated list. 
You may also repeat the match or pmatch filters multiple times. In this case, 
all strings and/or regular expressions must match.
