macOS has a bunch of US keyboard shortcuts Apple never documented.
There are riches at the bottom of this TidBits story — a list of shortcuts that use the Fn key instead of command, option, or control. Some are easier than Apple’s listed alternatives (like using Fn-F versus the hand-contorting Control-Command-F to enter fullscreen.)
This delights me, a person who rages when using any interface that doesn’t support tabbing between text input fields.
