The code below provides two functions that you can bind to
article-mode keys:

   lynx_view_article:
     View the current (html) article using lynx

   lynx_filter_article:
     Filter the current article with lynx

I believe the second one is the one you want.  Before using these,
please upgrade to the version pre1.0.3-6 that is in the git repository:

   git://git.jedsoft.org/git/slrn.git

Hopefully you will find this useful.
Thanks,
