About
FlyKey (键指如飞) is a Mac app that displays the keyboard shortcuts of the app you're using. The website describes it as a way to improve Mac efficiency by helping you quickly learn an app's shortcut operations.
To use it, double-tap the Command key. FlyKey then shows a list of all the current app's shortcuts. The website says it works for displaying both Mac system shortcuts and app shortcuts.
FlyKey runs natively on Apple M-series and Intel chips.
