Hi Hans, I love the style used for this manual. I tried to do the same thing, but it's a long way off ! I tried to find the source code to inspire me :-) I did this : \startuniqueMPgraphic{titled} path p ; p := unitsquare xscaled \overlaywidth yscaled \overlayheight ; pickup pencircle scaled 1mm ; linecap := squared ; drawoptions(withcolor \MPcolor{darkred}) ; draw ulcorner p -- urcorner p ; setbounds currentpicture to p ; \stopuniqueMPgraphic \defineoverlay[titled][\uniqueMPgraphic{titled}] \startuseMPgraphic{triangledone} fill lltriangle scaled 4cm withcolor darkred; \stopuseMPgraphic \defineoverlay[triangledone][\useMPgraphic{triangledone}] \def\Triangledone#1% {\framed [background=triangledone,frame=off,offset=overlay] {\tfb\color[white]{\bf#1}}} \startuseMPgraphic{triangledtwo} fill lrtriangle scaled 4cm withcolor darkred; \stopuseMPgraphic \defineoverlay[triangledtwo][\useMPgraphic{triangledtwo}] \def\Triangledtwo#1% {\framed [background=triangledtwo,frame=off,offset=overlay] {\tfb\color[white]{\bf#1}}} \setupheadertexts[margin][][\Triangledone\pagenumber][\Triangledtwo\pagenumber][] \setupfootertexts[margin][] [{\framed [background=titled,frame=off,offset=8pt,align=left, width=\dimexpr\leftmarginwidth-\leftedgewidth\relax] {\darkred\getmarking[section]}}] \setuppagenumbering[alternative=doublesided,location=] \setuphead [section] [color=darkred] \starttext \startchapter[title={First Chapter}] \startsection[title={First section}] \dorecurse{5}{\input knuth} \stoptext Thank you Fabrice
