How did you do that? I can see the benefit of killing them with the
mouse rather than having to reach for the Escape key.

I know I can just hit the Escape key but I use the mouse extensively so I
went so far as to create a button on one of my toolbars that kills the
marching ants! It's a lot faster for me just to use the mouse.
