Question : CKEditor: How to update textarea using javascript?

I've been through the CKEditor docs and the EE area but still can't find a solution to what I believe is a very simple problem: I am using CKEditor on a textarea, but wish to be able to manually clear out the textarea with javascript when the user presses a 'clear this field' button.

I set up a javascript handler for the button click, but I can't seem to clear the field out.

In the older FCKEditor code I could just use code like this:
document.myform.artistbio.value="";
CKEDITOR.updateContent("artistbio");

But the updateContent() is not in CKEditor (or at least I am not invoking it correctly?)

How can I call the CKEditor to clear out this field from javascript?

Thanks experts!
