It is mentioned in the tutorial http://matplotlib.sourceforge.net/tutorial.html#toolbar2 and in the "toolbar2" section if the user's guide. There are other nifty nuggets in there, like zoom to point in the zoom mode. > Adding the key support to the zoom-to-rect definitely would help. This seems like a god piece of low hanging fruit. Another feature that a couple of folks have mentioned to me off list would be in an constrained zoom to rect, to have the ylim (optionally) autoscale over the y data in the zoomed region.
