It does a few other things like:

• Removing the query parameters from the URL (like ?whatever=12)
• Closing the help popup
• Closing the theme list if open
• Blurring the focus from the search input

I'm not a big fan of this listing, even more since I'm sure it might do more things in the future (and I very likely forgot some of them...). However I don't have an idea on how to improve it... Maybe some from @rust-lang/rustdoc has an idea?

I also don't feel this change makes sense. esc here doesn't do anything out of the ordinary; people expect esc to escape from a particular view. If we were using esc like Emacs, as a control key, then I think it should be documented, but none of these seem particularly helpful to document to me.

I think "↑" and "↓" don't do anything out of the ordinary, but they are documented. Considering that, I think esc should also be documented. Is it not necessary to explain what esc does?
If so, does anyone have the way to improve the listing?

[GuillaumeGomez]

Both arrows definitely do something "out of the ordinary". You don't expect to be able to go through search results by simply pressing up and down arrows from the search input.

@GuillaumeGomez
Hmm. I think different people have different thoughts and we should define what is ordinary thing in this case. Anyway, I accepted your opinion. I'm going to close #82474 and this pull request.
