OS X Mavericks: Change modifier keys
Change the behavior of the following modifier keys: Caps Lock, Control, Option, and Command. This is useful if you’re familiar with a keyboard layout different from your current keyboard.
For example, the Control key on UNIX and Sun computer keyboards is located where the Caps Lock key is located on the Apple keyboards. For experienced touch typists, this can be awkward. Changing behavior of the Caps Lock key to Control solves this problem.
- Choose Apple menu > System Preferences, click Keyboard, then click Modifier Keys.
- Choose an action from the pop-up menu next to the modifier key you want to change, then click OK.
To return the keys to their original settings, click Restore Defaults.
