Yes "Show Results in Buffer" is key. I didn't understand this button either.
Also, is it possible to make Super+Alt+B toggle it? Reaching for the mouse and hitting such a tiny button ain't a great use of time. :)

Control-0 to focus and up/down/left/right/enter work great but it doesn't support typeahead. If I hit 't', I would be expected to be taken to files beginning with 't'. Instead, alphanum keys just seem to be ignored.
I'm not sure this item is actually complete yet.
