Disable “enter”

This plugin rocks!

Is there a way to stop users from hitting “return” or “enter”?

I ask because if I enter the first three letters of an artists’ name, I get great results, and even the artists’ name tag in the on-page results.

But if I type in the first three letters and hit “return” (as impatient users might) I get a new page with no results.

Am I missing something?
