systemManager.stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownListener); My test was lower-level than that, but it should call keyDownListener.

I'm not sure how to listen to the stage... I put the listener in the component with the canvas that is the parent of the objects... I assume the stage is at a higher level in the hierarchy? How would I pass the event back down to the canvas that needs it? Note that this canvas/container did get an activate event when I came back, and in that event's handler I added the listener, but nothing happened.
