To use a keyboard shortcut, press a modifier key at the same time as a character key. For example, pressing the Command key (it has a ? symbol) and then the "c" key copies whatever is currently selected to the Clipboard. This is also known as the Command-C keyboard shortcut. You can see the keys that map to many shortcuts by looking in an app‘s menus.
A modifier key is a part of many keyboard shortcuts. A modifier key alters the way other keystrokes or mouse/trackpad clicks are interpreted by OS X. Modifier keys include: Command, Shift, Option, Control, Caps Lock, and the fn key. These keys are represented by special symbols when you see them in menus and other parts of OS X:
| ? | Command key |
| ? | Control key |
| ? | Option key |
| ? | Shift Key |
| ? | Caps Lock |
| fn | Function Key |
When the fn key is used with the top row of keys on your keyboard, it makes them perform a different function. For example, if a keyboard shortcut is Control-F2, you can press fn-Control-Brightness on your keyboard.. If you look closely at the Brightness key at the top of your keyboard, there is an F2 symbol indicating that this key works as a function ey (F2 or function 2) when you hold fn on the keyboard.
If you use a non-Apple keyboard that includes a Windows key, the Alt key is the same thing as pressing Option, and the Windows key is the same thing as the Command key. You can change how these keys are interpreted from the Keyboard pane of System Preferences.
You can use these shortcuts in most apps to cut, copy, or paste a selected item. This includes text, pictures, music, and more. You can even copy and paste files in the Finder to copy them to a new location.
| Key combination | What it does |
| Command-C | Copy the selected data to the Clipboard |
| Command-X | Remove the selected item and place a copy on the Clipboard |
| Command-V | Place a copy of (paste) the Clipboard contents into the current document or app |
Use these shortcuts to take a picture of what you see on your screen. You can also use Grab to take screenshots, an app located in the Utilities folder.
| Key combination | What it does |
| Command-Shift-3 | Capture the screen to a file |
| Command-Shift-Control-3 | Capture the screen to the Clipboard |
| Command-Shift-4 | Capture a selection of the screen to a file, or press the spacebar to capture just a window |
| Command-Shift-Control-4 | Capture a selection of the screen to the Clipboard, or press the spacebar to capture just a window |
Use these key combinations to change how your computer starts up. Press and hold the key or combination of keys immediately after starting your Mac until the expected function occurs or appears. For example, press and hold the Option key during startup until the Startup Manager appears.
Note: If you‘re using a keyboard manufactured by someone other than Apple, the Alt key is usually the same key as the Option key. If this modifier doesn‘t appear to work, try using an Apple keyboard instead.
