I got tired of having to zoom in 10 or more times to reach my desired camera view. So I made this little addon that allows you to change the speed of the default Blizzard zoom in and zoom out.

Two new keybindings will appear at the bottom of the keybinding list - fast zoom in, and fast zoom out. Change your default zoom in and zoom out keys to these, and your zoom will work five times faster. The speed can be adjusted by typing /Fastzoom X, where X is a number from 1 to 50. The Blizzard speed is 1. The fastzoom speed is 5. Setting it to 50 will zoom to minimum and maximum with one press.

The default Fastzoom keybindings are Ctrl-mousewheel down, and ctrl-mousewheel up, since this is what I use. Feel free to change them.
