javascript - Set textarea selection in Internet Explorer

Question

I'm looking for a way to set a selection in a textarea in Internet Explorer. In other browsers, this works just fine:

textarea.selectionStart = start;
textarea.selectionEnd = end;

In IE, I assume I have to use createRange and adjust the selection somehow, but I cannot figure out how.

Extra bonus points for a link to a proper documentation about createRange and associated methods, MSDN isn't helping out much.

This works for me:

<textarea id="lol">
noasdfkvbsdobfbgvobosdobfbgoasopdobfgbooaodfgh
</textarea>

<script>
var range = document.getElementById('lol').createTextRange();
range.collapse(true);
range.moveStart('character', 5);
range.moveEnd('character', 10);
range.select();
</script>
