[NTG-context] Change whitespace before item?

Say I want to change the whitespace before an item in an enumeration. The diagram below: |.....(a) Item 2 |.....(b) item 2 Say I want to change the whitespace (represented by the dots) in a list? How can I do that? Tried various settings: changing margin, adding hskip, but nothing seems to do the trick. There doesn't seem to be anything in the docs... How can I get a question answered on this list, BTW? It seems that no one either knows anything or are too busy for simple questions. FYI, devs, this language is going to die if you don't get more users....
