Prova questo (bisogna mantenere il click sui pulsanti)
codice:

<TITLE>Selezione da una lista digitando i caratteri in un TextBox</TITLE>
<style type="text/css">

.inverted {color:white;background-color:navy}

</style>
<SCRIPT>
<!--
//var previousCell = null;
var stopScrollLeft=true;

var aliasTable = null;
var scrollStep= 2;
function pippo() {
if (aliasContainer == null || aliasTable == null) {
// return;
} // if (aliasContainer == null || aliasTable == null)
if (! stopScrollLeft) {
document.getElementById('t').value = aliasContainer.scrollLeft;
ScrollLeft();
} // if (! stopScrollLeft)
if (! stopScrollRight) {
document.getElementById('t').value = aliasContainer.scrollLeft;
ScrollRight();
} // if (! stopScrollRight)
} // function pippo()
window.setInterval("pippo()",15);
function ScrollLeft() {
if (aliasContainer.scrollLeft > 0) {
aliasContainer.scrollLeft -= scrollStep;
} else {
aliasContainer.scrollLeft = 0;
return;
} // if (aliasContainer.scrollTop > 0)
} // function ScrollLeft()
function ScrollRight() {
if (aliasContainer.scrollLeft <= aliasTable.offsetWidth - aliasContainer.offsetWidth) {
aliasContainer.scrollLeft+= scrollStep;
} // if (aliasContainer.scrollLeft <= aTable.offsetWidth - aliasContainer.offsetWidth)

function stopScroll() {

} // function stopScroll()
function setScrollObjects(aContainer,aTable) {

potrebbe essere buono, ma si blocca una volta cliccato sul pulsante... cioè non si ferma più lo scrolling, arriva alla fine.
