Zoom in/out of graph with scroll wheel

I hope it isn't gauche to post this notification, but this was terribly useful for me so I thought it would be of general interest. I just uploaded a procedure file that allows you to use the mouse scroll wheel to zoom in and out of a plot. As far as I know, Igor, by default, allows one to zoom one axis at a time with the scroll wheel, but not, for example, both the x and y axes simultaneously.

- Zooming is centered around mouse cursor
- Tries to pick the right axes to zoom (might have trouble on very complex graphs)
- Enable manually on one graph at a time or automatically enable on all new graphs
- Can temporarily disable by holding down control

I've been meaning to write this for years. Now that I have, I better go back to what I was really supposed to be doing.

I fully expect to now find out that this was enabled in the last release of Igor.
