[Doc]: Can't scroll with arrow keys

[tmost-utilidata]

📚 The doc issue

If I visit https://docs.vllm.ai/en/latest/ and press the down arrow key on my keyboard the page doesn't scroll. Page Down does seem to work.

Suggest a potential alternative/fix

It looks like there is a documentation search feature on this page that activates when I type a letter. It must have a broad key event listener to achieve this. It should ignore the arrow keys (i.e. not call preventDefault() on their events) until it activates.

Before submitting a new issue...

• Make sure you already searched for relevant issues, and asked the chatbot living at the bottom right corner of the documentation page, which can answer lots of frequently asked questions.

Turns out arrow key navigation is being intercepted somehow by the "Ask AI" widget in the docs.

I tested removing it in a local environment and arrow key navigation started working.
