Blender 2.6 - how do I edit Symmetrize options in the edit menu?

It always does it along one axis, but I want it to do it on another axis. How do I change it?

As with all other tools in blender look in the bottom of the toolshelf or press F6 for more options



Ah, thank you! Unfortunately it didn’t do what I had hoped, though. The bottom half of my model still doesn’t look like the top half.
