[NTG-context] different interlinear space for quotation?

Hi there, I have a text in which I want the interlinear space in narrower environments and the font size to be smaller. I tried something like the sample below, but it doesn't work (no suprise :-(). \startsetups[setups:narrow] \setupinterlinespace[line=2.8ex] \tfx \stopsetups \definenarrower[narrowlines][left=4em, setups=setups:narrow] \definelines[narrow][before={\blank\startnarrowlines[left]},after=\stopnarrowlines\blank] \stopsetups \starttext \input ward\par \startnarrow \input knuth\par \stopnarrow \input ward\par \stoptext Does anyone know how can I achieve a smaller font size and interlinear space only in narrower environments? Many thanks for your help, Pablo -- http://www.ousia.tk
