There are hundreds of keyboard shortcuts for Mac users. There are Mission Control shortcuts, Finder shortcuts, system shortcuts, application shortcuts and more. Many you can find by just looking through the menu bar for that application. You can find system ones by looking in the System Preferences under Keyboard.
But some keyboard shortcuts are more useful than others. And some are harder to remember than others.
