How to disable accidental submission after hitting ENTER/RETURN

Is there a feature that will enable/disable the form from being "submitted" automatically when the user hits the "enter/return" key?

I had a client fill out the form and instead of hitting "tab" to get to the next field, they hit "enter/return" and it submitted the form before they had completed it. I would like to know if something could be disabled so that they have to physically hover the mouse over the "submit" button and click it to actually submit it.

Thank you!

You can set some field which is important or need as REQUIRED. To do this, you click the field Properties and then turn on the REQUIRED switch.

This way it will show an error if you click submit while the field that are marked REQUIRED is empty.

You can also add a captcha field for extra security and ensures your form will not be submitted multiple times.
