That's I signature you don't see often. How about EqualsListeral?

That said, I think something like this would work cleaner:

  native nsDirection(nsDirection);

up front in the IDL and then

  [noscript, notxpcom] nsDirection getSelectionDirection();
  [noscript, notxpcom] void setSelectionDirection(nsDirection aDirection);

for the actual declaration.  That will give your C++ the function signature:

  nsDirection GetSelectionDirection();

I believe.

r=me with that.

I filed http://www.w3.org/Bugs/Public/show_bug.cgi?id=13411 to fix the wording of the selectionEnd setting part in the spec.

I don't see why we can't.  Would you mind filing a bug for that?
