Ask HN: how to KB select "New York" in dropdown lists?

Any US State that has a space in it is painful to type to completion because when I type space, my browser resets to any word and I'll jump instead of "Yukon" or something.

Anyone have an idea of how to choose a selection with a space inside a dropdown list?

Sorry to populate Ask HN with such mundanity but I couldn't think of a more avid group of life hackers except for possibly somewhere in a vim/emacs forum.
