How do I press the Fn key using a PC keyboard on a Mac?

You can use an application like ControllerMate to assign custom actions/scripts to keys and controllers.

The Function keys (F1, etc) behave as such (as opposed to brightness, volume, etc), regardless of what you set in the Keyboard preference pane. If you press “F Lock” the F keys simply do nothing. Luckily the F Lock remembers its setting across reboots.

There is no Fn modifier key as on the Mac keyboards.

KeyRemap4MacBook allows you to map the F keys to the usual brightness, volume, etc. but then you’d lose the normal F keys.


The Fn key on mac keyboards is a hardware driven feature.

What are you trying to accomplish?

I have a Microsoft Wireless keyboard attached to my MacBook Pro and can do much of what the function keys do from this -- once I installed the drivers.

enter image description here

For example, I can:

  • hit the volume, mute keys and play/pause to control audio
  • hit the "mail" key to go back to mail
  • I have F keys for Exposé features (e.g. F9 for all windows display, F10 for application windows

(Note that in Keyboard Preferences, I have "Use all F1, F2, etc. keys as standard function keys" checked)

I think the only feature that Fn provides that I cannot duplicate on the Microsoft keyboard is brightness control
