Hello all, when i do: \setupindenting[yes, next, big] \starttext \startitemize[columns, two][indentnext=no, symbol=star] \item {\it Loxodonta africans} (1216 bp) \item {\it Elaphas maximus} (1216 bp) \item {\it Mammut americanum} (1215 bp) \item {\it Mammuthus primigenius} (1284 bp) \stopitemize \input tufte \startitemize[indentnext=no, symbol=bullet] \item {\it Loxodonta africans} (1216 bp) \item {\it Elaphas maximus} (1216 bp) \item {\it Mammut americanum} (1215 bp) \item {\it Mammuthus primigenius} (1284 bp) \stopitemize \input tufte \stoptext the indentnext key is ignored in the following paragraph when i use [columns, two] before but symbolkey works (see attachment). Eventually Bug? best regards Bernhard
