Feature Request: Focus Next or Submit on Enter

Hi, I have been considering keyboard based rapid data entry scenarios. The settings 'SelectOnFocus' and 'Autofocus' are very useful. I think two more settings, FocusNextOnEnter and SubmitOnEnter would compliment them nicely.

FocusNextOnEnter would simply emulate a Tab button press when the return or enter keys are pressed. SubmitOnEnter would submit the form when the return or enter keys are pressed.
