Well, part of the problem is that you took the RN man page too literally. When it said &switch {switch} it meant &<your-switch-here> <more-switches-here-if-you-want> So the above can be properly rewritten (I think) as: { %(%m=[ap]?&+harticle-i.d. +happroved +hdistribution +hexpires\ +hfollowup-to +hmessage-id +hnf-from +hnf-id +hnewsgroups \ +horganization +hpath +hposted +hposting-version +hreply-to\ +hreferences +hrelay-version +hsender +hxref:) But there's an easier way to turn all the headers on. Specify an empty string for the "h" switch. That is: &+h From the RN man page: -h<string> hides (disables the printing of) all header lines beginning with string. For instance, -hexp will disable the printing of the "Expires:" line. Case is insigni- ficant. If <string> is null, all header lines except Subject are hidden, and you may then use +h to select those lines you want to see. You may wish to use the baud-rate switch modifier below to hide more lines at lower baud rates. You don't specify the "reasons which defy human comprehension," but if it's just to look at all the headers from one or two articles, you should know about the "v" command (for "verbose") at the article selection level.
