When entering information on the lead, you need to enable the reverse lookup based on the Zip Code alone. So, instead of entering City, then Zip Code, if someone just enters Zip Code, then it will populate the city and state automatically yet still allowing for the user to override the pre-populated fields.
Otherwise, you need to rearrange the form to follow a City -> State -> Zipcode entry because I want to be able to type City [tab] State [tab] Zipcode.
This would be very helpful. It would cut down on keystroke errors and effectively help with spelling of city names which are long and tedious to enter over and over again.
