Yeah, I actually find that annoying. Why would I want to move the plot within a window?

Anyway, when I've used plot(), if I hold the shift key down, a zoom-rubberband box appears. I think that should be the
default and the plot-move action the one made active using the shift key. I would also like the middle mouse button to
back out the zooming-steps, and the right mouse button return the plot to the original scaling (I know the window button
down the bottom does that but I don't want to have to move my mouse all the way down there everytime I want to rescale
-- my wrist and forearm muscles are getting sore!)

cheers,
