twebrowser as WYSIWYG editor

Hi,

Can anyone point me to the right place for information on creating a WYSIWYG
editor, I can put the twebrowser into edit mode load a html file no problem
but i could do with some sort of reference on how i can check the current
cursor position and change dropdown boxes to display the right font, size
etc as I want to put a full html editor in my Delphi app.

I am using Delphi 6 on winxp pro SP2

any links or advice greatly needed

thanks in advance.
