I would like to vary the typesetting of chapter titles by formatting the elements chapternumber, title and the word 'chapter' myself. However, the style values of the parameter setup from \setuphead[chapter][] should be used. Needed for this is access to and/or the naming scheme of the paramters: style, textstyle, numberstyle, color, textcolor, numbercolor. To clarify further, in \def\mychaptercode#1#2{...} \setuphead[chapter][command=mychaptercode] the #1 parameter gives the chapternumber typeset in a form that is just not how I want it. Thus instead of using #1 in the code for \mychaptercode I am using \headnumber[chapter]. But then cannot imagine how to set the right style and color. Finally, how is the macro containing the expansion for the chapter,sectiion-designation recalled? It is the macro defined by for example \setuplabeltext[chapter=Hoofdstuk ]. The reference manual does not reveal this as far as I can see. Yhanks in advance for either an answer or a pointer where to find the info. Hans van der Meer
