Mess With Your Modifier Keys

In System Preferences, go to Keyboard and then look for the Modifier Keys button. Click it and you’ll get settings for exchanging one modifier key for the other. For instance, you can switch the Option key and the Control key. Not so useful normally, but if you are using a third-party keyboard and don’t like how it is set up, then can help. You can also disable the Caps Lock key, which can be useful.
