Arrow keys don't move through search modal results in the v3 beta

I open the search modal with Ctrl+K and type a query, and I get a result list, but the up/down arrow keys don't move through it -- I have to reach for the mouse to pick a result.

Resolution: This was a gap in the early v3 beta search modal and was fixed in a later beta: the modal now behaves as a proper combobox, so up/down move through the results and Enter opens the highlighted one. The fix came with a behaviour change worth knowing about -- opening a search result now shows it in a floating panel rather than navigating to the full page. Hold Shift while opening a result to get the full page instead, or change the default in settings if you want the old behaviour back.
