[NTG-context] Spacing between text and footnote line

Hello, how an I change the distance between the text and the line of the footnotes? See this min-example: \setuplayout[grid=yes] \showgrid \starttext First sentence.\footnote{Test.} \dorecurse{5}{\input knuth} \stoptext That produces two lines distance between the footnote-line and the last line of the text on the first page. How can I reduce or increment it? Thank you! Huseyin -- Huseyin Özoguz E-Mail: h.oezoguz@mmnetz.de
