<form name=aaa>
This is GGG: <input type=text name=ggg><br>
This is HHH: <input type=text name=hhh>
</form>
<script type="text/javascript">
function dofo() {
document.aaa.hhh.focus();
}
</script>
<body onLoad=dofo()>
-We create an HTML form and name it aaa because that is easy to type and remember.
-We name our first text field ggg because we have a cat named G
-We name our second text field hhh because we want to.
-We write a little function and call it dofo because we think that is a clever name.
-document.aaa.hhh.focus();
---document - is the object we are manipulating, this page.
---aaa - is our form name.
---hhh - is the element name we want to place the focus on.
---focus() is a built-in Javascript method that places focus, the cursor in this instance.
-We call the function in our HTML body tag using onLoad.
When the page with this script loads, the cursor will be in the second text field, hhh.
