Thanks for your reply, Marco. Here is a full example: \starttext \definehead[Exercise][subsection] \setuphead [Exercise] [after=] \startExercise[]{(this is the exercise's title)} The exercise's content. \stopExercise \stoptext After contexting it, it looks like: 1 (this is the exercise's title) The exercise's content. Actually, I would like to have the head's number and the head's title on the same line. That is, whith no new line. Jean-Guillaume
