when either of the next/prev buttons are focused, should the arrow keys trigger navigation?

Currently arrow keys trigger navigation when using the markers, because they're a radio group, which also means they cycle around. Should the same behavior be applied to a focused next/previous buttons?

Radio-button-like behavior would not naively accomplish this with the buttons since they perform a relative navigation rather than absolute, and only perform this behavior on interaction. I'd be curious whether there are any established precedents for this.

In my experience, there is no expected behavior that a focused arrow/pagination button be triggered with the left/up or right/down arrow keys. This functionality can easily be be added by a custom script if the use case calls for it.
