I think this changed one of the last betas. When I bring up F&R the first time after starting Windows the focus is inside the list and not the input field.
So I cannot just start typing. I have either to click inside the field or close it and bring it up again.
Also I think that when I start typing while the focus is in the list and I'm not typing one of the shortcut numbers, the field should get the focus automatically and all I type in should go there.
