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 Wolfgang
