Re: defining font family for several options

[jbf <roma83537@gmail.com>]

Thanks Otared. That clears up that little item :-)

BTW I know how to reduce font size in the headers (chapter titles) that 
appear on the recto pages, which I can do with something like 
\setupheader [style={\ss\switchtobodyfont[10pt]}], but it doesn't seem 
to affect the header (title of the book) on the verso pages, which is 
drawn from the simple statement:

\startdocument
   [metadata:title={Book title}]

Shouldn't  \setupheader affect both headers? Or is it possible I have 
left something out of my \setupheader declaration?

I believe this aspect of things is now clear to me. No hurry, but when you have a moment can you explain the significance of the ~ in the {\bf\ss #1.~#2}}part of the definition, before the 2nd element?

I still have a couple of other queries (not font related) about things that are not functioning as they ought at the moment, which means I'll need either some understanding or some tweaking, but as always there are people on the list like yourself who are prompt with their assistance.

Maybe I shouldn't bother the list with these extra bits so am writing off list. Here is what my font definitions now look like (new one highlighted):

But if I don't set up the newly-defined [mychapterfont] then it is not recognised when I call it in. So what am I doing wrong? You see, I seem to back to the very first question I asked, which involved setting up two separate bodyfonts. So what is it I haven't understood?

Is that possible? In which case I could also use hw as well for a different typeface as well?). As you can see, I am trying to get to grips with this whole typeface issue which I find a bit complicated.
