Dear Hans, Thank you to answer my question. I've tried it and I'm sorry to report that this only works in MK IV, that I don't use (I've tried but some of my documents don't translate correctly). From my point of view, I don't know if it is the correct answer because I want to get some altered page number, and I think that I have to alter them "artificially", only for display purpose. best regards, Pierre-François Bonnefoi.

Hello,
I'use extensively context to write my lecture notes and for all of my printing needs.
For my students, I've made some lecture presentations in color, and I print them in black&white, with four pages on one page for the handout.
I would like to compute a correct Table of contents according to the handout : so to divide the current page number by four to get a correct page number for the handout.
\def\ChapterPrefix#1{\the\numexpr#1/4 \relax} \setupcombinedlist[content][level=1] \setuplist[chapter][after=,before=,numbercolor=yellow,numbercommand=\underbar,pagecommand=\ChapterPrefix]
That doesn't work, and I've some difficulties to figure how computation is performed in e-TeX...
Could you help me to resolve this issue ? \starttext
\setupuserpagenumber[way=bychapter]
\dorecurse{3}{\chapter{test} \dorecurse{4}{test \page}}
\stoptext
