Use the Modify Group dialog box to specify the groups
  whose remarks you want to replace.

  You can specify groups by first selecting
  (highlighting) them in an active group view window
  or by explicitly specifying them in the Group field
  by specifying a group name, a wildcard character, a
  wildcard character combined with a group name, or a
  list of these separated by commas.

  You also use this dialog box to enter the remark text
  that you want to replace existing text.
