It's pretty simple to find all of the threads on this forum referencing this... and some about thumb wheels. Click
Advanced Search, enter "thumb" (minus the quotes) and select search titles only. There's a reason Google is a multiple billion dollar company, the greatest landing spot on the internet and the makers of this forum software, not. The default search field on every Forum page is just not that useful on a forum of this size. The software makers of this forum are only slightly better than yours truly at search programming. This forum's default search is not intuitive, does not perform auto correction, and has zero artificial intelligence, but if provided the proper instructions is actually quite good at finding content, and in this case returns a pretty amazing amount of information if drill down to all the results. I lean heavily on Google's search tools as well, but many times get better results doing this. YMMV. See example below.
