type something in the search bar, after the result-list is rolling down under the bar. try to use the error key "down" to move to the list from the bar without to use the mouse to reset the mouse pointer.
this would be a perfect usability optimization in my opinion.
right now it is not possible to jump with the curser keys in the search list from the input form. how does the rest of you see that? I'm a creature of habit and love working with the keyboard
