Can't use keyboard to select item when there is only one result

[VNRg1d]

Version: 6.0.0 (281) Platform: OS X

Replication steps:

1. Enter a search term such that multiple items appear. You can cycle through them using the up/down arrow keys.
2. Enter a search term such that only one item appears. You cannot access this item using the arrow keys, tab, or any other combination of keyboard shortcuts I could find.

Expected behavior: items should be selectable using a keyboard shortcut so one doesn't need to use the mouse. Thanks!
