Prem Bhalerao. 4 min read. Jul 20, 2024. The function keys or F-keys on a computer keyboard, labeled F1 through F12, are keys that have a special function defined by the operating system, or by a currently running program.

Use the keys as standard function keys\n\n For example, pressing both Fn and F12 (speaker icon) performs the action assigned to the F12 key instead of raising the volume of your speakers. If your keyboard doesn't have an Fn key, try pressing and holding the Control key when pressing a function key.
