Increase the size of an AutoComplete feature

I've found this tutorial (really well done) in the internet : http://www.xtydigitaldesign.ca/autoComplete.php

I've started to use it and change it a little. But I can't find a way to increase the size font of the text of the list. (when you type "P" you get a list with four fruits that start with the letter P.) I've found how to increase the font size of everything, EXCEPT the font siez of the list..

Do you know how can I increase the font size of this list ?

Thank you very much !

I think it is in this part of the code, but I'm not sure :

    acList = new List();
    acList.x = 0;
    acList.y = acTxt.y + acTxt.height;
    acList.setSize(_txtWidth, listHeight);
    acList.visible = false;
    acList.addEventListener(Event.CHANGE, listHandler);
    addChild(acList);
