Good morning. First of all: Many thanks for you last hints -- it solved a lot of my problems. But one more is still present. I want that the ``text'' in the content list to be ``clickable'' (interactive) and of some color. But the color make a problem. Why something like this causes errors? % output=pdf \setupcolors[state=start] \setupinteraction[state=start, color=interactioncolor] \definecombinedlist[content] [section, subsection] [criterium=all, level=subsection] \setuplist[section] [interaction=text] \starttext \placecontent \section{First} \input tufte \section{Second} \input tufte \section{Third} \input tufte \stoptext I got this very error message: (./int1.tuo !
