What Event is Triggered on Save Click in ckEditor?

I've added a ckeditor editor instance to my asp.net application. Now, I want to capture when the user clicks on the save button in the ckeditor toolbar - but I haven't been able to find what ev开发者_运维知识库ent is triggered by ckeditor when the save button is triggered. Does anyone know?

I think this question that I asked a while ago may be relevant. One of the CKEditor developers suggested the getData event.
