Done that - got confused :o)

*sigh* ... all that assign function stuff is still very new to me.  All
I ever did was <assign|blah<macro|...>>.

Yes, I noticed that but, for example, for "author", I couldn't figure
out where the string "BY " gets added.

I know that - I already have a package which has stuff like

I see.

Perhaps documenting the various preamble constructs would be a good
idea.  That way, people can just make their own, and use as much of the
TeXmacs pre-defined stuff as they want, and no more than is necessary.

Nonetheless, thanks for the help :o)
