tips uses the "mouse enter/leave" events so you'll need to fire the "mouseenter" event on the element you want the tip to display on, then set an interval to fire a "mouseleave" event on that element later.
EXAMPLE:
<script type="text/javascript">
window.addEvent('load',function(){
var mytips = new Tips('.tips',{
fixed:true,//tip must be fixed for this to work
offsets:{x:125,y:0}
});
var wait = setInterval(function(){
clearInterval(wait);
document.getElement('.tips.auto').fireEvent('mouseleave');
}, 5000); //5 seconds
document.getElement('.tips.auto').fireEvent('mouseenter');
});
</script>
<div class="tips" title="header::this is the tip">text to tip</div>
<div class="tips" title="header::this is the tip">text to tip</div>
<div class="tips" title="header::this is the tip">text to tip</div>
<div class="tips auto" title="header::this is the tip">text to tip</div>

Due to the nature of Tips one can only display a single tip at a time. For more functionality you'll need to extend Tips to create/manage separate tips for each element.
