[Accessibility]: Notepad: Possibly unclear relation between arrow selection behavior and tab/focus behavior

Keyboard navigation

User journey audit issue

https://github.com/sourcegraph/sourcegraph/issues/34198

Problem description

In order to select an item with a keyboard, it needs to be focused (via Tab) and then can be selected by pressing Space. This is also how multiple entries can be selected (Tab to entry and press Meta + Space). But selecting an item with ↑/↓ keys does not move focus.

Selecting a range items can only be done via Shift+↑/↓ and doesn't move focus either.

Expected behavior

It's actually not clear to me how focus should change wrt to arrow up/down keys.
