[NTG-context] Formatting enumerations in MKIV

I am trying to configure an enumeration in MKiv, but it is not clear how to set some of the formatting. I need to be able to control the distance between the title and the enumeration text, but parameters such as 'inbetween' seem to have no effect. Is there a parameter I can use to set the spacing. Also, how do I find out what parameters are available. I tried to figure out where defineenumeration is defined in the lua or mkiv files without luck. \starttext \defineenumeration[ref][alternative=left,inbetween=\blank] \ref Testing \par \ref Testing \par \stoptext -Lance Larsen
