A double hung window is provided with a keeper on the upper pane that also provides an elongate surface for receiving a downward force for moving the upper pane. The keeper has a tongue provided on an inner side of a central web of the u-shaped member that forms the combined keeper and surface. The force-applying surface is provided on a vertically upper surface of the same central web. The force-applying surface is curved along a slight radius such that it comfortably accommodates the fingers of a user to provide the downward force.
