What specific section or headline is this issue about?

You should avoid using this if possible; it's been deprecated for some time. Instead, you should use KeyboardEvent.code, if it's implemented.

What information was incorrect, unhelpful, or incomplete?

The page https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/keyCode recommends using KeyboardEvent.code instead of the deprecated KeyboardEvent.keyCode:

You should avoid using this if possible; it's been deprecated for some time. Instead, you should use KeyboardEvent.code, if it's implemented.

But the overview page https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent recommends using KeyboardEvent.key in this section:
https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent#:~:text=KeyboardEvent.keyCode

Warning: This property is deprecated; you should use KeyboardEvent.key instead, if available.

What did you expect to see?

I would expect both places to recommend the same approach to replacing the deprecated keyCode. Maybe it would be best to explain that using key or code depends on the use case and give a very brief explanation of the difference between the two.
But if only one alternative is suggested, I'd say that in a clear majority of cases key makes more sense.

Do you have any supporting links, references, or citations?
