This generates a really annoying features with some browsers. Suppose I want to select "United Kingdom". I open the drop-down and there are all the countries in alphabetical order, plus "United States" at the top of the list. I hit the 'U' key. It does not take me to the alphabetically listed countries beginning with 'U', it takes me to the "United States" entry at the top of the list. I might be able to type 'U-N-I-T-E-D-K' and get to the "United Kingdom" entry, but there are browsers where that does not work. (Nor does repeatedly hitting 'U' bring me to the later 'U' entries.)
