Need help on hitting "Enter" key to trigger a button...

Hi,

I'm trying to make the "Enter" key function exactly the same as clicking on the Find button that has an ' OnClientClick="return validateForm()" ' and does a PostBack. In other words, if the user hits the "Enter" key on his keyboard after filling in the zip code, I need the "Enter" key to do exactly as clicking on the "Find" button.

Thanks very much in advance.

<script type="text/javascript" src="/js/jquery-1.2.1.js"></script>

    <script type="text/javascript">

        // <![CDATA[

        function validateForm() {

            var zipCode = $("input#<%= txtZipCode.ClientID %>").val();

            zipCode = $.trim(zipCode);

            var state = document.getElementById("<%= ddlState.ClientID %>").value;

            var objZip = document.getElementById("<%= txtZipCode.ClientID %>");

            if (zipCode == "" && state == "") {

                alert("Please enter a zip code or select a state!");

                objZip.focus();

                return false;

            }

            if (zipCode != "" && !validateZipCode(zipCode)) {

                alert("Please enter a valid zip code!");

                objZip.focus();

                return false;

            }

            

            return true;

        }

        

        function validateZipCode(v) {

            var regex = /^\d{5}$|^\d{5}-\d{4}$/;

            return regex.test(v);

        }

        // ]]>

    </script>		
 

    <div>

	<form id="form1" runat="server">

        <table border="0" cellpadding="2" style="width:500px">

            <tr id="trZip" runat="server">

                <td style="text-align:right;vertical-align:top">Select a state</td>

                <td style="text-align:left">

                    <asp:DropDownList 

                    ID="ddlState"

                    DataTextField="StateName" 

                    DataValueField="State_ID" 

                    AppendDataBoundItems="true" 

                    Runat="server">

                    <asp:ListItem Text="Select State" Value="" />

                    </asp:DropDownList>

                    <br /><br />

                    <asp:Button ID="btnFind" Text="Find" OnClick="btnFind_Click" OnClientClick="return validateForm()" Runat="server" />

                </td>

            </tr>

        </table>

		

        <asp:ObjectDataSource

            id="srcState"

            TypeName="State"

            SelectMethod="SelectStates"
