[TYPO3-project-formidable] Submit form on enter keypress

[Gary Wong]

I have a couple of searchform fields. I would like the searchform to 
submit when the user types something in either of the boxes and press 
ENTER.  I  looked over the onkeypress code and while I can get what's 
typed in the field I have no idea how I can capture the ENTER key 
press.  I don't mind using client JS or AJAX.  Anyway have any ideas?

Thank you,
Gary
