Here are my most used shortcuts for navigating OS X:
|⌘ + Spacebar||Spotlight (to quickly open documents, applications, and more)|
|⌘ + tab||Switch between applications|
|⌘ + `||Switch between windows in applications|
|⌃ + tab||Switch between tabs in a window|
Commands, Universal and Local
Universal commands are general commands that the operating-(OS X, Windows, Linux)-system uses, and they often work in most applications too—like Command + C (copy) and Command + V (paste).
Local commands are unique commands that are defined by the application.
Learning universal commands is usually the first learning priority. If you are mostly working out of a specific application, it will definitely help to prioritize learning those local shortcuts too.
