Mac shortcut guides
One page per Mac shortcut worth knowing: the keys first, then when to use it, the faster alternative, and the setup the Setup Kit uses.
Lock screen
Press Control-Command-Q to lock your Mac. Plus the Touch ID key, a hot corner that never fires by accident, and the setting that makes a sleeping display lock.
Full screen
Control-Command-F turns full screen on and off on a Mac. When full screen helps, why Fill usually works better, and the shortcut that fills a window instead.
Show desktop
Show the desktop on a Mac with Fn-F11 or a trackpad spread. Why there is no minimize-all-windows shortcut, and the hide shortcuts that work better.
Hot corners
Set up hot corners on a Mac in Desktop & Dock settings. Which actions earn a corner, the modifier-key trick against accidents, and the one corner we keep.
