I certainly did not mean to desparage Frank Klaus with my "parlor trick" comment. He has been an idol of mine for many years. John's description and clarification of my use of the term "parlor trick" is spot on. I think the technique is s eye-catching for sure, but of limited value to us mere mortals, unless we're in a production environment where it might save some time. Consequently, while I certainly enjoyed watching Frank perform this amazing feat, I don't think I'll be spending my time trying to master it.
Thanks, John, for the clarification.
