Article Hiding
--------------

   Or rather, hiding certain things in each article.  There usually is
much too much cruft in most articles.

`W W a'
     Do quite a lot of hiding on the article buffer
     (`gnus-article-hide').  In particular, this function will hide
     headers, PGP, cited text and the signature.

`W W h'
     Hide headers (`gnus-article-hide-headers').  Note: Hiding
     Headers.

`W W b'
     Hide headers that aren't particularly interesting
     (`gnus-article-hide-boring-headers').  Note: Hiding Headers.

`W W s'
     Hide signature (`gnus-article-hide-signature').  Note: Article
     Signature.

`W W l'
     Strip list identifiers specified in `gnus-list-identifiers'.  These
     are strings some mailing list servers add to the beginning of all
     `Subject' headers--for example, `[zebra 4711]'.  Any leading `Re:
     ' is skipped before stripping. `gnus-list-identifiers' may not
     contain `\\(..\\)'.

    `gnus-list-identifiers'
          A regular expression that matches list identifiers to be
          removed from subject.  This can also be a list of regular
          expressions.

`W W p'
     Hide PGP signatures (`gnus-article-hide-pgp').  The
     `gnus-article-hide-pgp-hook' hook will be run after a PGP
     signature has been hidden.  For example, to automatically verify
     articles that have signatures in them do:
          ;;; Hide pgp cruft if any.
          
          (setq gnus-treat-strip-pgp t)
          
          ;;; After hiding pgp, verify the message;
          ;;; only happens if pgp signature is found.
          
          (add-hook 'gnus-article-hide-pgp-hook
                    (lambda ()
                      (save-excursion
                        (set-buffer gnus-original-article-buffer)
                        (mc-verify))))

`W W P'
     Hide PEM (privacy enhanced messages) cruft
     (`gnus-article-hide-pem').

`W W B'
     Strip the banner specified by the `banner' group parameter
     (`gnus-article-strip-banner').  This is mainly used to hide those
     annoying banners and/or signatures that some mailing lists and
     moderated groups adds to all the messages.  The way to use this
     function is to add the `banner' group parameter (Note: Group
     Parameters) to the group you want banners stripped from.  The
     parameter either be a string, which will be interpreted as a
     regular expression matching text to be removed, or the symbol
     `signature', meaning that the (last) signature should be removed,
     or other symbol, meaning that the corresponding regular expression
     in `gnus-article-banner-alist' is used.

`W W c'
     Hide citation (`gnus-article-hide-citation').  Some variables for
     customizing the hiding:

    `gnus-cited-opened-text-button-line-format'
    `gnus-cited-closed-text-button-line-format'
          Gnus adds buttons to show where the cited text has been
          hidden, and to allow toggle hiding the text.  The format of
          the variable is specified by these format-like variable
          (Note: Formatting Variables).  These specs are valid:

         `b'
               Starting point of the hidden text.

         `e'
               Ending point of the hidden text.

         `l'
               Number of characters in the hidden region.

         `n'
               Number of lines of hidden text.

    `gnus-cited-lines-visible'
          The number of lines at the beginning of the cited text to
          leave shown. This can also be a cons cell with the number of
          lines at the top and bottom of the text, respectively, to
          remain visible.

`W W C-c'
     Hide citation (`gnus-article-hide-citation-maybe') depending on the
     following two variables:

    `gnus-cite-hide-percentage'
          If the cited text is of a bigger percentage than this
          variable (default 50), hide the cited text.

    `gnus-cite-hide-absolute'
          The cited text must have at least this length (default 10)
          before it is hidden.

`W W C'
     Hide cited text in articles that aren't roots
     (`gnus-article-hide-citation-in-followups').  This isn't very
     useful as an interactive command, but might be a handy function to
     stick have happen automatically (Note: Customizing Articles).

   All these "hiding" commands are toggles, but if you give a negative
prefix to these commands, they will show what they have previously
hidden.  If you give a positive prefix, they will always hide.

   Also Note: Article Highlighting for further variables for citation
customization.

automatically.
