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?

I've done this a few times using the built-in superscript. For example:

This is an example of additional information1 being added to a post.

1 Here is the additional information.


This is an example of additional information<sup>1</sup> being added to a post.
<sup><sup>1</sup> Here is the additional information.</sup>

This seems to work pretty well for most situations.

  • Thank you very much :). This is nice enough for my actual need.

On MacOS, I’ve used Unicode Hex Input to enter them.
