                </ej:MenuItem>

            </Items>

        </ej:Menu>

Add the following code example in your script section.

JS

jQuery(function ($) {

        //Control focus key

        $(document).on("keydown", function (e) {

            if (e.altKey && e.keyCode === 74) { // j- key code.

                $("#<%=MenuControl.ClientID%>").focus();

            }

        });

});

Following screenshot displays the output of the above code example.

When you press Alt+J the first item, the Menu control only gets focused as illustrated in the following screenshot.

Similarly you can access the Menu control by using keyboard itself.
