I have a user who is looking to understand the "Logic" that SureType uses to search the address book. He would like to search more efficiently.....

For Example:

When contacts in the address book I press the "GH" key to search. Sometimes it will start with the G and other times it starts with the H. How does Suretype which character it will select first. I know that if you backspace and then hit the same key the next character will come up but I need to understand the method (if there is one.)

maybe it goes for the most frequently used?
