[Pharo-project] how to capture pasting in a textmorph

Hi, I have a PluggableTextMorph, and I would like to get notified every time the text contents change. Currently, I intercept keystroke:from:, but the problem is that this does not capture pasting of text. Is there a better hook? Cheers, Doru -- www.tudorgirba.com "Value is always contextual."
