What is the FN button on a laptop?

The FN button, short for “Function,” is a special key located on the bottom row of most laptop keyboards, typically near the control keys. It serves as a modifier key, similar to the Shift or Alt keys. By holding down the FN key and pressing one of the function keys (F1 through F12), users can access additional features and shortcuts that are not available with just the function keys alone.

These additional features often include hardware controls, such as adjusting volume, brightness, screen resolution, and even enabling or disabling certain hardware components like Wi-Fi or Bluetooth. The exact functionality of the FN button can vary depending on the laptop manufacturer and model, making it a key part of many users’ daily interactions with their devices.
