Like this, by word of mouth. That’s how Apple has done UI design since they stopped printing paper manuals.

- ctrl-shift-. to show hidden files on macOS - pull down to see search box (iOS 18) - swipe from top right corner for flashlight button - swipe up from lower middle for home screen

Etc, etc

So that’s why Reader mode sometimes shows up directly when I click on the icon, I must be long clicking it by accident.

cmd+shift+R for reader mode if you prefer a keyboard shortcut
