Fix horizontal scrolling in Chrome: defaults write com.google.Chrome AppleEnableSwipeNavigateWithScrolls -bool FALSE and restart Chrome. Fix autoscroll with AutoScroll.

Minimized windows don't even appear in Chrome's autocomplete!

Disable MacOS widget popover gesture via System Settings, "trackpad gestures", More Gestures, Notification Centre off.

Windows shortcut equivalents:

Alt+Enter or F11 = Cmd+Ctrl+F or Globe+F
Alt+Tab = Cmd+Tab (Switch app.) or Cmd+` (Switch app window.) No minimized windows. Witch is a bit slow but can cycle windows with Opt+Tab like Windows does, including the browser window you minimized to get to the one behind it, albeit without thumbnails. AltTab is better, also because it doesn't raise all w

Audio

Latitude 5501 sounds even worse than my MSI MS-16P7 due to ratting its plastic case. Interviews sound like a poor phone connection. Iron Maiden - Can I Play With Madness on the other hand is tolerable and even has some bass, almost enough for Robbie Williams - Angels, which sounds like a not-quite-tuned FM radio for the vocals (too little power), particularly noticable on U2 - Discotheque. Without "audio enhancements" disabled, its audio jack adds a rumble to videos like this. Worst audio hardware I've ever used, especially playing this. Then again, using my
