Ouch, sorry! That means I didn’t even check if that mode existed before; I also swapped the if/else brackets.

Yes, that works. Thank you very much!

i.e. MWE =

\setupinteraction[state=start]
\defineprocessor[kursiv][style=italicface]

\define[1]\Idx{\doifmodeelse{*footnote}{\index[kursiv->]{kursiv->#1}}{\index{#1}}#1}

\appendtoks
   \setsystemmode\currentnote
\to \everysynchronizenote

\starttext

Text

---
\index[C]{A}{B}\footnote{Inside\Idx{FN}}\Idx{BF}
---

\placeregister[index][criterium=all]

\stoptext
