Hi, probably my question is not a very hard one but I don't find a way to do what I'm trying to do. If I use \cite[authoryears] ConTeXt uses last names in the citation. That's what I want, but I want to use another style for my task, that I defined this way: \definebtx[aps:cite:margin][authorconversion=normalshort] \startsetups btx:aps:cite:margin \texdefinition{btx:aps:title} \texdefinition{btx:aps:author} \doiftextelse\currentbtxrighttext{ \currentbtxrighttext } { \removeunwantedspaces \removepunctuation } this works and is perfect for my style, but I obtain the full names, and not just the last names. How can I obtain something similar to the citation I'm using, but with just last names?
