// Scrolling text functions
//
// Each field needs its own function for DIV targeting, and also for the boolean trigger
//
// works as follows:
// - first line displays the size-limited substring of the current message
// - next line lops a single character off and moves it to the end of the string
// - final line waits a give time interval, and then calls the function again
