What you’re looking for is the \definefont command, in one way a low level
method to access a font
but also a usefull command to create styles for headings etc.
Let me start with the following example:
\definefont[Test][texgyrepagellaregular at 12pt]
\starttext
\Test VA ffl
\stoptext
What I do here is to create the new command \Test which loads the file
“texgrepagellaregular”
at a size 12pt. With the optional prefix on front of the font name you can
specify the search method,
context provides the three different methods a) file b) name and c) spec.
a) \definefont[Test][file:texgyrepagellaregular]
b) \definefont[Test][name:texgyrepagellaregular]
c) \definefont[Test][spec:texgyrepagella-normal-normal]
Instead of a fixed size for the font you can also use a relative size which
depends on the bodyfont.
\definefont[Test][texgyrepagellaregular sa 1]
\starttext
\Test VA ffl \switchtobodyfont[20pt]\Test VA ffl
\stoptext
When you use “sa XX” as argument for the size your font scales also when you
change the bodyfont
in the middle of the document.
One problem of the definitions above is that kerning, ligatures etc. aren’t
activated for the font
because no feature isn’t applied. To apply a feature set you have to use a
different method than
the one which is used in a typescript because \definefont has no feature-key.
What you have to
do to apply the set is to append it after the name name and separate both with
a asterisks.
\definefont[Test][texgyrepagellaregular*default sa 1]
\starttext
\Test VA ffl
\stoptext
Instead of the real name of a file you can also use a symbolic name from a
typescript.
\definefont[Test][SansBold sa 1]
\starttext
\Test VA ffl
\stoptext
In this example I used the bold version of the sans style for my \Test font, in
this case
you don’t have to add the name of a feature because it has been already set in
the typescript.
A complete example in a document could be look like this:
\definetypeface[mainface][rm][specserif][Antykwa Poltawskiego]
\definetypeface[mainface][ss][specsans] [Iwona]
\definefont[ChapterStyle][SansBold sa 3]
\setuphead[chapter][style=ChapterStyle]
\setupbodyfont[mainface]
\starttext
\chapter{Knuth}
\input knuth
\stoptext
