In other words, nngoback can mark news\narticles which have arrived on the system during the last days days unread.\n\nOnly  subscribed  groups  that  occur in the current presentation sequence are rewound.  That\nmeans that if no group arguments are specified, all groups occurring in the sequence  defined\nin  the init file will be rewound.  Otherwise, only the groups specified on the argument line\nwill be rewound.\n\nWhen a group is rewound, the information about selections, partially read  digests  etc.  are\ndiscarded.  It will print notifications about this unless the -Q (quiet) option is used.\n\nIf  the -i (interactive) option is specified, nngoback will report for each how many articles\ncan be marked unread, and ask for confirmation before going back in that group.\n\nIf the -v (verbose) option is specified, nngoback will report how many  articles  are  marked\nunread.\n\nIf the -N (no-update) option is specified, nngoback will perform the entire goback operation,\nbut not update the .newsrc file.\n\nIf you are not up-to-date with your news reading, you can also use nngoback to  catch  up  to\nonly have the last few days of news waiting to be read in the following way:\nnn -a0\nnngoback 3\nThe nn command will mark all articles in all groups as read (answer all to the catch-up ques‐\ntion.)  The following nngoback will then make the last three days of news unread again.\n\nExamples:\n\nnngoback 0\nMark the articles which have arrived today as unread.\n\nnngoback 1\nMark the articles which have arrived yesterday and today as unread.\n\nnngoback 6\nMark the articles which have arrived during the last week as unread.\n\nYou cannot go more than 14 days back with nngoback.
