Limiting
========

   It can be convenient to limit the summary buffer to just show some
subset of the articles currently in the group.  The effect most limit
commands have is to remove a few (or many) articles from the summary
buffer.

`/ /'
`/ s'
     Limit the summary buffer to articles that match some subject
     (`gnus-summary-limit-to-subject').

`/ a'
     Limit the summary buffer to articles that match some author
     (`gnus-summary-limit-to-author').

`/ u'
`x'
     Limit the summary buffer to articles that are not marked as read
     (`gnus-summary-limit-to-unread').  If given a prefix, limit the
     buffer to articles that are strictly unread.  This means that
     ticked and dormant articles will also be excluded.

`/ m'
     Ask for a mark and then limit to all articles that have not been
     marked with that mark (`gnus-summary-limit-to-marks').

`/ n'
     Limit the summary buffer to the current article
     (`gnus-summary-limit-to-articles').  Uses the process/prefix
     convention (see Process/Prefix.).

`/ w'
     Pop the previous limit off the stack and restore it
     (`gnus-summary-pop-limit').  If given a prefix, pop all limits off
     the stack.

`/ v'
     Limit the summary buffer to articles that have a score at or above
     some score (`gnus-summary-limit-to-score').

`/ E'
`M S'
     Display all expunged articles
     (`gnus-summary-limit-include-expunged').

`/ D'
     Display all dormant articles
     (`gnus-summary-limit-include-dormant').

`/ d'
     Hide all dormant articles (`gnus-summary-limit-exclude-dormant').

`/ c'
     Hide all dormant articles that have no children
     (`gnus-summary-limit-exclude-childless-dormant').

`/ C'
     Mark all excluded unread articles as read
     (`gnus-summary-limit-mark-excluded-as-read').   If given a prefix,
     also mark excluded ticked and dormant articles as read.
