To enable the F3 key on your Mac, you can follow these steps:
1. Start by clicking on the Apple menu located at the top-left corner of your screen.
2. From the dropdown menu, select “System Preferences” to open the System Preferences window.
3. In the System Preferences window, click on “Keyboard.” It is usually located in the second row.
4. Once you are in the Keyboard settings, click on the “Keyboard Shortcuts” tab, which is positioned at the top of the window.
5. In the left sidebar of the Keyboard Shortcuts tab, click on “Function Keys.” This will display a list of all the function keys on your keyboard.
6. Look for the F3 key in the list and make sure it is selected. If it is already selected, then the F3 key is already enabled. If it is not selected, continue to the next step.
7. At the bottom-right corner of the window, you will find a small “+” symbol. Click on it to add a new shortcut.
8. A new window will appear, allowing you to add a custom keyboard shortcut. In the “Menu Title” field, type the name of the function or application you want to associate with the F3 key.
9. After entering the Menu Title, click on the “Keyboard Shortcut” field and press the F3 key on your keyboard. This will assign the F3 key to the selected function or application.
10. click on the “Add” button to save the new shortcut.
Once you have completed these steps, the F3 key on your Mac will be enabled and assigned to the function or application you specified. You can now use the F3 key as intended.
It is worth noting that certain applications or system functions may already have specific functions assigned to the F3 key by default. In such cases, you may need to modify or disable those existing shortcuts to use the F3 key for your desired function.
