Not really. It takes less than a second to click on that link, much longer to open the manual and turn to page 78, which I had overlooked in my reading, and read the couple of paragraphs on "paths", which backs into the Song Button routine. Besides that, the manual is in my reading room, beside the porcelain reading pedestal. I'm afraid to take the laptop in there because it might fall in and get wet.
Anyway, it seems nobody much remembered this until I brought it up, although it appears to be a very useful feature.
