[NTG-context] Divider in grid environment

Dear All, I'd like to use a divider between certain paragraphs. As I want to keep all the lines on the grid so it should have a height = N x line height. As \hl renders the line on baseline, I have to tweek the space before/after using the 'blank' command to keep the horizontal line in the +/- middle: \setuplayout[grid=yes] \showgrid \showlayoutcomponents \starttext \input{ward} \blank[4mm]\middlealigned{\hl[4]}\blank[6mm] \input{ward} \stoptext But this solution requires adjustments for different fonts or font sizes... Is there a more efficient way how to accomplish this? Thanks, Jan
