Configure Feature Dialog Box - Select all or select none?

I love the new "Configure Feature" function, but there aremany times when I'm using it that I need to select every checkboxor unselect every checkbox.

I don't see a button to do this, is there a quick way to do it thrukeyboard shortcuts or something like that?

I tried control or shift selecting but all it seems to do is makethe surrounding box turn black, but doesn't affect the check markat all.
