Thanks for your long and prompt reply. It was your document on creating a
layout that I looked at. It looks very well written and clear, as do
several other documents of yours I have looked at. I have done a lot of
programming in the past, but I think your estimate of a day to get to grips
with it, is somewhat optimistic. Perhaps a week for a finger tip grip is
more realistic for someone who is not even conversant with a lot of the
subject of layout terminology. I appreciate your prolific enthusiasm and
desire to get me more involved. I must admit you make it tempting.
However the idea of writing one from scratch is too much to think about at
the moment. I know enough to know there is a huge amount about layout
issues that I have never considered. So my worry is that even if I wrote a
basic layout, I think I could then spend years struggling with spacing
issues to avoid widows, children, uncles and whatever else is out there.
So the next thing I looked at was Guenters' suggestion of using a
Document class of “book (KOMA-Script)”, or I assume that is what he meant.
Though even with this I still haven't found a full solution yet.

Thanks for that, the documentation for this is also good, and the whole lot
seems to operate at a higher level. So I experimented, first I tried
editing the preamble….
\usepackage{scrpage2}
\usepackage{titlesec}
\setkomafont{chapter}{\ttfamily \bfseries\huge}
This gave me some control over the chapter font, which as a default also
seems to have less space above the text than the standard Lyx, which is
what I required. However the header (now lacking a page number) was almost
touching the text on flowing pages, so I tried some commands to control the
header. This one placed in the preamble to control the font worked...
\renewcommand{\headfont}{\normalfont\sffamily\mdseries}
However so far it is the only one to do so.
I have also tried putting the page number back with …
\ohead{\pagemark} and \ohead{\pagenumber} in the preamble and when that
failed as inserted Tex code. Neither seem to be recognised in either
location. Ignored on the preamble and causing an error when inserted as ERT.
( I presume "pagemark" could be anything )
So I now have a “solution” with the chapter heading, but a now a problem
with the page header.
