Puzzle Trouble

Hi people, This is my first thread, I’m not sure how this works exactly but here goes. I’m attempting to put together an interactive crossword puzzle in flash mx, but I am having trouble with the inputting of the text. I need the curser to jump to the next square after the previous letter has been typed. Check out this link for a good example http://www.webcrosswords.com . If anyone has any better ideas feel free to enlighten me.
