I don't seem quite able to put it all together, forgive the question. I have a 'Bookman' font setup, pretty vanilla: \definetypeface [Bookman] [rm] [serif] [bonum] [sl=name:unituscndboldoblique] \definetypeface [Bookman] [tt] [mono] [modern] [default] \definetypeface [Bookman] [ss] [sans] [unitus] [default] \definetypeface [Bookman] [mm] [math] [modern] [default] (Unitus is the fontsite 500 'Univers' substitute, works fine) Now, the built-in gyre bonum font doesn't have a slanted/oblique variant, so if I have Bookman as my main body font, \sl produces (unsurprisingly) the same result as \it, TexGyreBonum-Italic. If I want \sl to summon Latin Modern for the variant, I have tried variations on \definetypeface [Bookman] [rm] [serif] [bonum] [sl=file:Latin Modern Roman Slanted] but to no avail — not helped by the fact that the \definetypeface contextgarden page doesn't have any pointer to just what that fifth argument can contain.

How do I accomplish this?

Use \definefontfamily which is missing in your example.

\definefontfamily [Bookman] [rm] [TeX Gyre Bonum] [sl=features:{*,slanted}, bs=features:{*,slanted}]

\definetypeface [Bookman] [mm] [math] [modern] [default]

\setupbodyfont [Bookman]

\starttext \tf upright \it italic \sl slanted \bf bold \bi bolditalic \bs boldslanted \stoptext

Except that this does not work, because, as I said, the Gyre Bonum font has no builtin slanted version.

Have you even taken a look at the output of my example?

So, I want to use some other font (like Latin Modern) for a substitute for \sl .

I still think my version looks better (even with bold Latin Modern). \definefontfamily [slantedbookman] [rm] [TeX Gyre Bonum] [sl={style:regular,features:{*,slanted}}, bs={style:bold,features:{*,slanted}}] \definefontfamily [modernbookman] [rm] [TeX Gyre Bonum] [sl={file:lmromanslant10-regular}, bs={file:lmromanslant10-bold}] % \definefontfamily [modernbookman] [rm] [TeX Gyre Bonum] % [sl={file:lmromanslant10-regular,features:{*,boldened}}, % bs={file:lmromanslant10-bold,features:{*,boldened}}] \starttext \setupbodyfont [slantedbookman] \it italic \sl slanted \bi bolditalic \bs boldslanted \setupbodyfont [modernbookman] \it italic \sl slanted \bi bolditalic \bs boldslanted \stoptext Wolfgang
