Dear List, On the first page I had this example: \definepapersize[MyBook][width=19cm,height=29.7cm] \setuppapersize[MyBook][MyBook] % Prints on paper the size of MyBook %\setuppapersize[MyBook][A4] %Would print MyBook-size pages on A4 paper \setupbodyfont[modern, 12.50pt] \definemargindata [MyInMargin][inleft] \definemarginframed[MyInMargin][topframe=on,bottomframe=on,rulethickness=1pt,width=1.90cm] \defineenumeration [theorem] [ text=Theorem, title=yes, width=fit, distance=0.2em, alternative=serried, ] \definetextbackground[GrayBackground][ location=paragraph, background=color, backgroundcolor=lightgray, leftoffset=.5\bodyfontsize, rightoffset=.5\bodyfontsize, topoffset=.5\bodyfontsize, bottomoffset=.5\bodyfontsize, frame=off,] \margintext{\blackrule[color=black, height=0.10ex, width=1cm]\\} \blackrule[color=black, height=0.10ex, width=13.50cm] \starttext \margintext {1.1.1} {\bf Beispiel 3.2.17. (Vertauschung von All- und Existenzquantor).} \par So I have here an example from the second page: \definemargindata[inrightmargin][right][margin=margin,width=.50em\rightmarginwidth,style=,color=] \definemarginframed[MyInMargin][topframe=on,bottomframe=on,rulethickness=1pt, width=.90cm] \blackrule[color=black, height=0.10ex, width=13.40cm] {\blackrule[color=black, height=0.10ex, width=1cm, distance=.90cm]\par \defineenumeration [theorem] [ text=Theorem, title=yes, width=fit, distance=0.2em, alternative=serried, ] \inright{3.2.22} {\bf Theorem 3.2.22 (Rechenregeln für Quantoren)}. Seien \m P(\m x)und My problem here is that there is not the same distance between the the text and the margintext . And now the margintext should be on the right side. So maybe someone could help me please. Many thanks.
