[NTG-context] section head unnumbered but with dots in TOC ?

[Steffen Wolfrum]

Hi,

I am lost in ConTeXt's setup-jungle:


I have a section set is unnumbered:

\setuphead[LevelThree] [number=no, ...|


But in the TOC I would like to have a dot (or another symbol) before 
the head/title, like this:

o     Section's Title     17


Is this a matter of \setuphead or \setuplist? Or none of them?

How can it be achieved?
