[NTG-context] setuphead for in-paragraph head ?

Hi all, this is my first message here. In the subsection head, I would like to suppress the newline between the number and the text, so it behaves like some kind of numbered subsubject. I tried to modify some examples from the wiki, but without success. In http://wiki.contextgarden.net/Command/setuphead , most of the options are not explained. My purpose is to define something like: \definehead[Exercise][subsection] \setuphead [Exercise] [alternative=Mine?, ..., numberstyle=bold] So I can typeset a list of exercises in a compact way. I could use enumerations but I don't think I should. Thanks.
