How To Use Function Keys As Standard Keys In OS X

0 comments

In all Apple portables such as MacBook Pro and MacBook Air, we have functions keys which can be used for various functions such as brightness control, volume control, music playback etc. But if you want to treat the function keys as standard keys, it's easy. To change the setting follow the previous instructions.





  1. Choose System Preferences from the Apple menu.
  2. Choose Keyboard (or Keyboard & Mouse in Mac OS X v10.5.8 and earlier).
  3. Enable "Use all F1, F2, etc. keys as standard function keys."
Now you would be able to use all the function keys as normal keys on the OS X keyboard.
