I’ve been trying to define a layout that just has a 5mm no-printing edge around the paper and has all the rest for \textwidth and \textheight. No header, footer, pagenumber, etc. Just as much space as I can get out of a standard A4.

But the following (following the manual and ConTeXtgarden):

\setuplayout[leftedge=5mm,top=5mm,rightedge=5mm,bottom=5mm,
leftmargin=0mm,rightmargin=0mm,
margindistance=0mm,edgedistance=0mm,
topdistance=0mm,headerdistance=0mm,footerdistance=0mm,bottomdistance=0mm]
\showlayoutcomponents % doesn’t seem to do anything
\showframe % this works
\starttext
\input knuth
\stoptext

Doesn’t seem to change the layout. What am I missing?
