WebBrowser control select text and hover events

I'm in the process of developing a WinForm application that uses a WebBrowser control to display HTML content. I'm trying to subscribe to hover events and text selected events so I can display a popup bubble (or something similar). 

Does anyone know if this is possible?  If so, do you have some sample code?

If this is not possible using the WinForm WebBrowser control, is there another API I can use?

Thank you
