Setting up Transitive Keyboard Remapping on a Macbook: Caps Lock to Right Command Keys in System Settings
When setting up a new Macbook, one of the customizations that you might want to make is remapping the Caps Lock key to the Right Command key. This can be particularly useful for users who are coming from a Windows background and are more accustomed to using the Command key for shortcuts. In this article, we will go through the steps to set up transitive keyboard remapping on a Macbook, specifically remapping the Caps Lock key to the Right Command key in System Settings.
Prerequisites
Before we begin, it is important to note that this tutorial assumes that you have already set up your Macbook and have access to the System Settings. Additionally, you will need to have administrative access to your Macbook in order to make the necessary changes.
Steps to Remap the Caps Lock Key to the Right Command Key
Follow these steps to remap the Caps Lock key to the Right Command key in System Settings:
- Open System Settings by clicking on the Apple menu in the top left corner of the screen and selecting "System Settings" from the dropdown menu.
- In the System Settings window, click on "Keyboard" in the left-hand menu.
- In the Keyboard settings, click on the "Modifier Keys" button at the bottom of the window.
- In the Modifier Keys window, you will see a list of modifier keys and their corresponding functions. To remap the Caps Lock key to the Right Command key, click on the dropdown menu next to "Caps Lock" and select "Control" (or any other key you prefer).
- Next, click on the dropdown menu next to "Right Command" and select "Caps Lock".
- Click on the "OK" button to save your changes.
Testing the New Keyboard Layout
To test the new keyboard layout, simply press the Caps Lock key. It should now function as the Right Command key. Additionally, you can press the Right Command key (formerly the Caps Lock key) to confirm that it now functions as the Caps Lock key.
Troubleshooting
If you encounter any issues with the new keyboard layout, you can try resetting the NVRAM on your Macbook. To do this, restart your Macbook and immediately hold down the "Command", "Option", "P", and "R" keys. Continue holding these keys until you hear the Mac startup sound for the second time, then release the keys. This should reset the NVRAM and resolve any issues with the keyboard layout.
Remapping the Caps Lock key to the Right Command key is a simple customization that can make your Macbook more comfortable to use, especially if you are coming from a Windows background. By following the steps outlined in this article, you can easily set up transitive keyboard remapping in System Settings and start using your Macbook with a more familiar keyboard layout.
