Hello Everyone, A while back Aditya provided a patch for using *alternative=authornum* in *\cite*. The patch adds et al. for the cases with more than two authors. I have been using it without a hitch since then. However, today I tried to use *extras* option with this patch and it won't work. The MWE works for *alternative=apa* and *alternative=num* Please let me know if this can be rectified. Regards, Devendra *MWE* \setupbibtex[database={bib}] \unprotect \def\dobibauthornumref#1% {\bibinsertrefsep \doifbibreferencefoundelse{#1} {\begingroup \cite[left=,right=,alternative=author][#1]% \bibalternative\c!inbetween \cite[num][#1]% \endgroup} {}} \protect \starttext \cite[alternative=authornum,extras={,\S 5.1}][citation1] \placepublications \stoptext ----------- bib.bib ----------- @article{citation1, title = {Kernel independent component analysis}, author = {Bach, F.
