Disable Form Submit with the "Enter" Key
How to use:
Simply paste this code on any page (in the </ body> code section of the page settings) that has a form in which you would like to disable the enter/return key from submitting. if you have multiple forms throughout many different pages then it might be better to paste the code in the global Site Settings > Custom Code > </ body>. This can be very useful for stopping accidental key presses or to use in combination with the "Reveal Submit ButtonWhen Email is Validated" code crumb.
