how to include sans, bold and size in \setuptab[headstyle=???]

how to include sans, bold and size in \setuptab[headstyle=???]

[Lars Huttar]

Hello, I have the following MWE:
\starttext

\setuptab[headstyle=ssbfb]

\tab{foo} \input knuth \par

\stoptext


Here, the headstyle specifies a sans font with boldface style, at 1.44
times the current bodyfont size.


However, I want to be able to specify an absolute point size, instead of
a relative size.

I tried variations like

  \setuptab[headstyle=18pt]

but that has no effect: the size remains 12pt, or whatever the default is.

If I use
  \setuptab[headstyle={\switchtobodyfont[18pt]}]

then the size takes effect (for the key only, which is what I want).
I can combine that with sans:
  \setuptab[headstyle={\switchtobodyfont[ss, 18pt]}]

and that works.


But how to mix in boldface?
  \setuptab[headstyle={\switchtobodyfont[ssbf, 18pt]}]

doesn't give sans boldface, but reverts to a serif, non-bold style (at
18pt size).

  \setuptab[headstyle={\switchtobodyfont[ss, bf, 18pt]}]

gives the same results.


I finally tried

  \setuptab[headstyle={\ssbf \switchtobodyfont[18pt]}]

and that works! But it seems clunky: it looks like it requires two font
switches, which I'm told makes things slower.

And I can't help wondering if I'm missing some simpler way.
Is there a more efficient or elegant way to do this?


Thanks,
Lars

\definefont[BigBoldSans][SansBold at 18pt]

\setuptab[headstyle=BigBoldSans]

OK, but in order to use this systematically, I would have to have a
\definefont for every potential combination of font style (serif/sans),
alternative (bold/italic/etc.), and size that will get used in the
document. In a large, complex book, that extra layer of indirection
seems unattractive. But maybe there's no better way to do it.
