What is really in my clipboard? How does it interact with a webpage?

Question

When I copy some content on a web page, what really happens? What will be saved to the clipboard?

I once thought it was a plant of text, however I can paste its style or images into M$ Wordor some WYSIWYG web editors such as TinyMCE. And this is not html code, otherwise I will see tags in geditor Notepad.

My main questions are:

• where is the document that explains clipboard knowledge?
• When I make web pages, is it possible to control what users will copy to the clipboard using javascript?
