How to automatically move to the next field when current one is full ( phone, ssn entry, etc)
Allows you to auto advance to the next field when the user fills up the current field with data. Great for entering phone or social security numbers that are broken out into their seperate fields (i.e.: area code, exchange, phone number) so the user doesn't have to tab to the next entry point.
