Hi Hans and Alan, the argument of the command key for the \setupbtx command is shown twice in the running text. \usebtxdataset[mkiv-publications.bib] \setupbtx[command=\groupedcommand{<}{>}] \starttext \cite[article] \placelistofpublications \stoptext A possible fix for this is to change the name of one instance (publ-ini.mkiv) where the key is used from command to textcommand. \def\publ_cite_handle_variant_indeed[#1]% {\letbtxparameter\c!alternative\currentbtxcitealternative \edef\currentbtxreference{#1}% \saverunningstyleandcolor \usebtxstyleandcolor\c!style\c!color \uselanguageparameter\btxdatasetparameter % new \btxparameter\c!left - \btxparameter\c!command{\dobtxcitevariantblob}% {\publ_cite_handle_variant_blob}% + \btxparameter\c!textcommand{\dobtxcitevariantblob}% {\publ_cite_handle_variant_blob}% \btxparameter\c!right \endgroup} Wolfgang
