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.)
