I am working on a simple screen saver for my 9600 and 9800's, I am using the following script'

System.setGlobal("Screen_Saver", '5');
function Func ()
{
var ScreenSaver = System.getGlobal("Screen_Saver");
if (ScreenSaver > 0) {
ScreenSaver--;
System.setGlobal("Screen_Saver", ScreenSaver);
}else{
CF.widget("Clock_Jump", "IR", "XBOX").executeActions();
};
scheduleAfter(90000, Func);
}
scheduleAfter(5000, Func);

Each button on the page is using this,

CF.widget("XBOX_Pause", "IR", "XBOX").executeActions()
System.setGlobal("Screen_Saver", '5')
to send the IR command as well as to reset the count back to 5.

It works very well, my question is there a better way, such as a script that would monitor input from both firm keys as well from input from the touch screen?
Thanks,
