Within a question or answer is it possible to write a footnote?
For example, if I use a tricky term, for many readers, some of them will understand it at first reading, but some others might prefer a correct explanation. To do this within web pages or written technical documents I use footnotes.
Is this possible within StackExchange?
If not, could this feature be added?
What is the relevant StackExchange group wher to ask this question?
