Can you run an event from a return button?

Hi,

I was wondering whether you can run events from the return?

I have created single page forms that can run through different directions so my next and submit buttons are not the standard. currently when pressing return it doesn’t automatically run these. Is there a way I can force these to run if they’re visible on the page?

I’ve also got a widget that contains many boxes can I control inside the widget when a return happens?

Thanks
Robin
