Rich, here is a link to another way of doing the same hack (without requiring a stalk):

As Toolpants pointed out to me, some people (with long legs?) prefer a button instead of the 4th stalk as the stalk interferes with the movements required when changing gears etc. I'm 6'2", and I realized that Jeff was right - my left knee would make contact with the 4th stalk.
Oh, and nice job with your site - I've bookmarked it
