Any key on the keyboard but you have to slide up (swipe, basically) with a mouse instead of just clicking? I get it that it makes sense on tablets as a lock screen, but on desktops? Ok, I’m going to call that a bug and ignore it. It’s easy to fix and no big deal in the grand scheme of things.
Even with that changed and the hotcorners indicated, the hodgepodge stays, though. The hotcorners are only the tip of the iceberg, what you notice immediately. (Or, rather, not at all, like me, who figured out to use the Windows key pretty quickly – but still after some confusion – but didn’t find the hotcorners for a long time after that. I can totally identify with the guy in the video. I wasn’t quite as helpless, but close and I’m young and grew up with that stuff.)
