There is a nice "widget" in the contact us page letting the user search the help center:
When clicking the "search" button it works flawlessly and give back the results below the textbox.
However, if I press Enter the page posts back to itself, adding "?q=[search term]" to the URL of the contact page itself e.g. http://meta.stackoverflow.com/contact?q=questions which of course is not the desired action.
Can the Enter key press cause the search button to be clicked instead?
