You add a selection listener to the selection, which I believe
you can get via window.getSelection(). You can then QI to
nsISelectionPrivate (assuming you are in XUL), and call
add/removeSelectionListener.
Check out:

nsISelectionPrivate.idl#67>
Be aware that the selection changed callbacks can get called
a lot. You don't want to do too much work in response to them.
You might want to use a timer to do work only after the selection
has not changed for some period of time.
