I hope someone can help me.  I have a VF page that includes 4 tabbed sections.  One of them is a custom search tab.  When the user types their criteria (an account name) into the inputtext box, and clicks my search button, everything works great.  If the user types in their criteria, then presses "Enter",  the page refreshes and takes the user back to the first tab (my search tab is the fourth tab).
How can I get pressing enter to be the same as clicking the button?

Thanks in advance!!
