Auto select multicolumn combo box while typing

if we are using simple combo box with let suppose database. below is the example of datasource

1.     Florida    = FL

2.    NewYork  = NY

3.    New Jerssy = NJ

if user press N (combo box is selected) it will select New York and if user again press N it will select next item in the list New Jerssy. can we have same behavior with multicolumn combo box.
