OK, I forgot to mention that you need to call the base class's keyPressEvent()
method to handle any key presses that you aren't interested in.

Try adding an "else" clause to your keyPressEvent() implementation:

  else:
      QGraphicsView.keyPressEvent(self, event)

If you want the up and down arrow keys to do in-page scrolling, you'll need
to call this method instead of checking for those keys and doing something
different. Perhaps you mean to use the Qt.PageUp and Qt.PageDown keys for
navigation between pages?
