Does anyone know how to listen for a keypress, and if no field (or element) is selected, to have a default element to jump to? For example in TipIt, if the user starts typing, and they haven't selected a field, it should automatically go to the subtotal field

also, for some reason, even though I have all text fields with attributes of autoFocus: false, the subtotal seems to grab focus anyway. Anyone know how to fix that? Thanks!
