Yeah, that's the exact bit.  But like I said, it's rather short and
should contain a reference to mhshow.

Now that I read that ... context is probably the wrong term (the nmh context
has stuff in it like the current message, folder, etc).  mh-profile(5)
explains that in greater detail, but in this case it should be "profile".

Anyway ... check out the man page for mhshow.  And also mhn.defaults has
an example.

Sure.  Here's a sample line I used in my .mh_profile that I just
tested right now with the attach command; it did exactly what it was
supposed to do.

mhshow-suffix-application/pdf: .pdf


Ah, I didn't understand the thread correctly.  Yes, it should be profile
and not context.  My mistake, although it lasted for years :)

And yes, having defaults for common content types in the profile would
be a good thing.  At the time that I wrote this stuff suffixes were not
nearly as standardized as they are today.
