Dear ConTeXt folks, although looking at tex/texmf-modules/tex/context/third/letter/base/s-cor-01.mkvi on how to disable folding marks, I was unsuccessful to figure it out. This is with ConTeXt ver: 2012.08.28 20:00 MKIV fmt: 2012.8.29 int: english/english and please consider the following minimal example. \mainlanguage[de] \usemodule[letter] \starttext \setupletter [fromname={Max Musterfrau}, fromaddress={Beispielstraße 99\\99999 Musterstadt}] \setupletter [toname={Jane Mustermann}, toaddress={Musterstrarße 9999\\99999 Musterstadt}] \setupletterstyle [marking=no] \setupletter [marking=no] \startletter [opening={Sehr geehrte Damen und Herren,}, subject={Musterbetreff}, closing={Freundliche Grüße,}, signature={Max Musterfrau}] \input knuth \stopletter \stoptext Thanks, Paul
