You can use the right arrow for 'I'm feeling Lucky'.

If you hover over a result in the suggestion list, there's an I'm Feeling Lucky option on the right.

Heard Marissa Mayer say one time that while people don't use it they like the fact it's there (let's them know Google is fun and has a sense of humor).

It shows up when you hover over the suggestions.
