Ed,
Asp.net applications are designed that only one can control can capture the enter key event at any given time.
However, Kelly Ford believes:
"you can use some JS to set the key. If so, you could set the key when the search field textbox gets focus. This could be added via jQuery, regardless of XMod. This is assuming that I'm correct in how that works. I haven't had time to research."
Hope that helps in your research,
