Hi,

I needed to call the undo/redo functionality on a TextInputControl.

What I ended up was doing this:
((TextInputControlBehavior)((TextInputControlSkin)textArea.getSkin()).getBehavior()).callAction("Undo");

This uses internal classes.

I suggest to add those methods to the control, so that I can use:
textArea.undo();

However, I don't know, if this contradicts the Control/Skin/Behavior concept.

Maybe another solution is to put the Behaviors in the public package and add an undo/redo method to it, so that you don't have to callAction with a String value.

Other functions like copy/paste could be useful as well.
