PBasicInputEventHandler is the standard class in Piccolo that is used to register for mouse and keyboard events on a PNode. Note the events that you get depends on the node that you have registered with. For example you will only get mouse moved events when the mouse is over the node that you have registered with, not when the mouse is over some other node.
