To use a keyboard shortcut, or key combination, you press a modifier key with a character key.
A modifier key is a part of many key combinations. 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. If your keyboard has an Fn key, you may need to use it in some of the key combinations listed below. For example, if the keyboard shortcut is Control-F2, press Fn-Control-F2.
Here are the modifier key symbols on OS X menus (See http://support.apple.com/kb/ht1343 for original chart and more details):
| ⌘ | Command key |
| ⌃ | Control key |
| ⌥ | Option key |
| ⇧ | Shift Key |
