How Fn key on screen display?

The Fn key (Function key) on laptops and keyboards typically does not have a dedicated on-screen display, as it primarily functions as a modifier key to access secondary functions of other keys. However, some devices may show an on-screen indicator when Fn is used in combination with other keys, such as brightness or volume adjustments. This visual feedback can be helpful for users to confirm that the desired function is activated. To enable or disable this feature, users may need to adjust settings in the device's keyboard or accessibility options.
