**May I know what’s the mening stand for the setProperty… and from the if (Number(curZoom) == 0)**

on (release, keyPress “\<Left\>”) {  
if (Number(curxScroll)\<Number(maxXpos)) {

setProperty("/map", \_x, Number(getProperty("/map", \_x))+Number(intScroll));

if (Number(curZoom) == 0) {

curxScroll = Number(curxScroll)+Number(intScroll);

} else if (Number(curZoom) == 1) {

curxScroll = Number(curxScroll)+Number(intScroll/2);

}

if (Number(curZoom) == 2) {

curxScroll = Number(curxScroll)+Number(intScroll/4);
