Keeping track of new user selections in NSTextView

Hello all,

I'm looking for a  method in NSTextView
that gets triggered exactly when the user selects a portion of text
(and it gets colored blue ...). I thought
at first that the delegate method

-(void) textViewDidChangeSelection:(NSNotification*)aNotification

was what I needed, but after toying with it in the debugger I saw
little difference with -textDidChange: -textViewDidChangeSelection is
called just about every time
the user modifies the text. It seems that there always is
a "default" selection even when the user has actually selected nothing. So
where is
the method I need ?
