For my current project I want to use the keyup event on TextBox to grab the current value when "Enter" is pressed. Is it possible to include the forwarding of the event object to the event listener in future releases? It's only a small patch for the TextBox necessary to include this functionality.

Yes, I'm starting to see similar requests from people. Unfortunately it's not so simple to fix. I filed #5417 about it. In the meantime can't you just do a dojo.connect(myWidget.focusNode, "onkeyup", myHandler) ?
