Since no one has used addEventListener yet, here is my version. Given the elements:

I would use the following:

var go = document.getElementById("go");
var txt = document.getElementById("txt");

txt.addEventListener("keypress", function(event) {
    event.preventDefault();
    if (event.keyCode == 13)
        go.click();
});

This allows you to change the event type and action separately while keeping the HTML clean.

Note that it's probably worthwhile to make sure this is outside of a

because when I enclosed these elements in them pressing Enter submitted the form and reloaded the page. Took me a few blinks to discover.

Addendum: Thanks to a comment by @ruffin, I've added the missing event handler and a preventDefault to allow this code to (presumably) work inside a form as well. (I will get around to testing this, at which point I will remove the bracketed content.)
