[texhax] Twocolumn, fancyhdr, fix2col, marks and dictionaries

[Philip TAYLOR (Ret'd)]

Using the standard LaTeX document option "twocolumn"
with Piet van Oostrum's "fancyhdr" and David Carlisle's
"fix2col" styles, I have successfully generated
left and right page headings corresponding to the
headwords at the top of the left and the bottom of
the right column of each page (Attachment 1).

What I would like to be able to do, however, is to
emulate Cappelli's [1] style of headings, where his
left and right headers are themselves headword ranges :
the left header consists of the first and last headwords
in the left-hand column, separated by an en-dash, whilst
the right header consists of the first and last headwords
in the right-hand column, similarly punctuated.

My current code reads (in part)

     \markboth {\unexpanded {\textgreek {#5}}}{\textgreek {\unexpanded {#5}}}

     ...

     \renewcommand {\chaptermark}[1]{}
     \renewcommand {\sectionmark}[1]{}

     \pagestyle {fancy}
     \lhead {\rightmark}
     \chead {---\tie \thepage \tie ---}
     \rhead {\leftmark}
     \lfoot {}
     \cfoot {}
     \rfoot {}

where #5 contains the headword in extended Teubner notation.

I would be very grateful for any advice on how I should modify
this to emulate Cappelli's style of headings.
