Answering my own question....
I got the HWND of the window by calling self.ie.GetHandle() as
suggested in another message in this thread. Unfortunately that handle
is some distance ABOVE the true IE window in the hierarchy. So, I used
win32gui.EnumChildWindows to get all the children. Then using
win32gui.PostMessage I could send a WM_MOUSEWHEEL event to the IE
window to get it to scroll. I can also use WM_VSCROLL to make it scroll
down one page at a time like I wanted.
Thanks, this list is very helpful.
Now to edit the HTML to override font selections and to make links open
in another window.
