Scroll through the list by holding down the arrow keys

[BrianSiimAndersenEG]

I would very much like that it would be possible to scroll through the list of results by keeping the arrow-down key down. As of know you have to release the arrow-down key and press it again to scroll down to the next element the list. The regular comboboxes in Vaadin work this way.

If you need to go down the list a bit it would be nicer to just hold down the arrow-down key.

This behaviour also shows in the online demo.
