Autocomplete Tab/Enter

The keystrokes for Autocomplete are less than ideal. I start typing in the field and options come up. I now have to key down to the correct one, even if it’s the only option. I then have to press Enter to select that option. I then have to press Tab to go to the next field.

It would be great if when an option was selected it automatically filled the field and moved to the next field.

Also, if there was only one option left pressing tab would select that option and move to the next field.

I found a jsFiddle that shows what I mean. http://jsfiddle.net/trSdL/4/

Thanks,
