I also understood "optional keys" to be "in addition to" rather than an "option to have". I've now realized what's interesting about the way this website works is that it neuters the review process. The orders are reviewed after everybody gets their special product and sales are over. The other thing that sucks is that the keys don't have any resistance or click at all. I chose based on the descriptions provided by the vendor. I wanted this keyboard to be plug-and-play but it's cool, I'll just put it into a yard sale in 10 years. Email me if you want mine.
