Could you provide Message-IDs so I can see what you mean?

Message-ID?

Aah.  I see.  Actually I killfile all text/html only messages.  I
know it's ruthless.

Are you typing <esc>6 etc in group or article mode?  It works in
article mode, and group mode I see the command prefix message you
must be seeing.

#v+
define register_display_filters () {
  () = register_hook ("read_article_hook", "demime");
  () = register_hook ("read_article_hook", "t_prot");
  () = register_hook ("read_article_hook", "display_filter");
}

define unregister_display_filters () {
  () = unregister_hook ("read_article_hook", "demime");
  () = unregister_hook ("read_article_hook", "t_prot");
  () = unregister_hook ("read_article_hook", "display_filter");
}

register_display_filters ();

definekey ("register_display_filters", "\e6", "article");
definekey ("unregister_display_filters", "\e7", "article");
#v-

To get it to work in group mode:

#v+
definekey ("register_display_filters", "\e6", "group");
definekey ("unregister_display_filters", "\e7", "group");
#v-

If you don't mind mailing it or making it public, could I get a
copy of your script?  I'll try it out, and if it's better than
the perl demime will post instructions, credits, links etc on my
slrn page.
