A similar question has been asked three years ago, and Rik Kabel posted a partial solution, adapted here: \defineprocessor [Footnote] [right={ n}] \define[1] \fnindex{\index[Footnote->]{#1}} \starttext This is a sentence with a term in the index: cat\index{cat}. This sentence also has an indexed term, dog\index{dog}, as well as a footnote.\footnote{The footnote also contains an indexed term, mouse.\fnindex{mouse}} \page \placeregister [index] \stoptext And about a year ago, Hans made a different suggestion to my own question; however, I didn't realize then that it was not what I was looking for: \starttext Test1: \index{cat}cat. \footnote{Test2: \index{mouse}mouse.} \footnote[note:cat]{Test3: \index[cat]{cat in \in{note}[note:cat]}cat.} \page \placeregister [index] \stoptext This creates two index entries for cat, which is not the intended result. My questions are: 1. I would like to have the footnote number appear in the index, so it says something like "cat 1 n. 1." Is that possible? 2. Is it necessary to define an extra command for index entries in footnotes? Is context clever enough to know that it's processing a footnote, so one could write a condition such as (pseudocode): \define [1] \myindex {\infinfootnoteelse {\index[Footnote]->{#1}} {\index{#1}}} Thanks a lot, have a good Sunday!
