[NTG-context] Alignment, indenting and font inside floats

Dear list, I want to setup all my floats' contents to be middle-aligned, not indented and typeset in a distinct font. How can I do this? The attached example does not work. Thank you and kind regards, Joshua Krämer \setupindenting [yes, \the\baselineskip] \definefontfamily [figurefamily] [serif] [Latin Modern Sans] \setupfloats [align=middle, style={\switchtobodyfont[figurefamily]}, indenting=no] \starttext \input knuth \startplacefigure Word \stopplacefigure \stoptext
