Plot Zooming

Q: I know that you can change the PlotRange option to zoom into a plot region, but it is awkward for every zoom to use this option. Is there a way to zoom into a plot using the mouse?

A: Ingolf Dahl (ingolf.dahl@telia.com) answers: At library.wolfram.com/infocenter/MathSource/191 you will find a handy palette, written by Timothy Lottes, which is designed for this purpose. It works by controlling the ImageRegion parameter of the picture.
