Thanks for the quick reply! Unfortunately, that isn't it. (I had searched in the Extras forum as well). The one you link to cannot transfer more than one task at a time, and it requires some setup within the script, and edited iCal's urlPrefixes.plist.

It's possible the AS was simply written in a post, and I pasted it into Script editor. But I didn't have to do anything except put it in the script menu bar folder.

Thanks anyway. Maybe someone else remembers this, or even the one who wrote it?
If I knew anything about AS, I try to re-write it myself.
