Topic: Jquery | event on enter key press

Hey godbitters

Using jquery to add some ajaxy loveliness to a web app I'm developing. I'm editing a field in a db basically copying this http://15daysofjquery.com/quick-and-dirty-ajax/14/. at the moment the database isn't edited until the user clicks on the submit button. How can I fire the function when the user presses enter rather than just click the button?

Hope the query makes sense and you'll have me an answer

Thanks in advance

Richard
