Pamela, Both key drag zoom and DragZoomer are similar in function, except that DragZoomer doesn't use a mouse click to define the rectangle.
Instead, you press the shift key, and while holding the shift key, move the mouse. If a rectangle doesn't appear, it's possible that the map doesn't have keyboard focus. (Flash seems to behave as a second-class citizen within the HTML page.) In that case, you'll have to click the map once to give the map keyboard focus, and try again.
