Make clicking on the side make you focus on the main content

[Telov]

I like navigating websites using arrows on the keyboard. Usually to make them be applied to the main space of the page you click somewhere on the side, close to the scrollbar, but when I do it on the Bevy website I instead appear to be focused on the sidebar, meaning pressing the arrows affects the scrollbar of the table of contents, not of the page itself. Could it be changed to what I described as "usually"?
