When Action Keys mode is enabled, function keys will work as multimedia keys by default. So you can press a single function key (F1 – F12) to mute/unmute the audio, adjust the volume or project to a screen, without having to hold down the Fn key. If you am very used to using the F2 key to rename files, just disable Action Keys mode and you’re good to go.
On some DELL or Lenovo laptops, the Fn Lock key is the Esc key. Pressing Fn + Esc can enable or disable the Action Keys mode with ease.
fn key + esc key 조합으로 action key를 해제/또는 적용할 수 있다. 적용되었으면 F1 - F2 key들은 멀티미디어키로써 작동된다. 이는 코딩이나 엑셀작업을 할때 단축키 사용에 어려움을 주니 해제하고 사용하도록 하자.
