Change the behavior of the modifier keys on Mac
You can change the action that modifier keys, such as Control or Option, perform when you press them.
On your Mac, choose Apple menu > System Settings, then click Keyboard in the sidebar. (You may need to scroll down.)
Click Keyboard Shortcuts, then click Modifier Keys in the sidebar.
For each modifier whose default action you want to change, click the pop-up menu, then choose the action you want performed when you press the key, or choose No Action.
For example, if you’re used to a keyboard that had the Control key where the Caps Lock key is located on an Apple keyboard, you could click the Caps Lock pop-up menu, then choose Control to have that action performed whenever you press the Caps Lock key.
To return the keys to their original settings, click Restore Defaults.
