input field bypassing by <enter> w/o form submission

input field bypassing by <enter> w/o form submission

Dear jQuery's guru,
I faced a problem!
I want to bypass from one input field to other one by <enter> (<return>) key pressing instead of default behaviour (<tab> key pressing).
But there was default form action on <enter> keydown event was performed. Remember that <enter> keydown event on form means default "Form submit" action.
How to prevent default action, form submission, in time of <enter> keydown event processing?

How to modify following code? I use hotkeys jQuery plugin for key binding to input fields.

$().ready(function(){
  $(myInputFieldsSelector).bind('keydown','return',function(evt){
    //find next input field in the form MyNextInput
    MyNextInput.focus().select();
    //stop event propagation and prevent default action
    return false;//didn't work - form submission was happened
  });
}

Thank you for advice!
