Hello

Using a standard IBM compatible USB keyboard with a Mac mini and can't access the brightness and volume controls with the function keys. Is it possible to enable them? Other function keys are enabled F9-F11 (Dashboard) and F12 (Eject). The other F keys behave as normal with Mac OS X shortcuts. The keyboard has F1-F12 keys. With Apple's remote control it is possible to access the brightness and volume controls.

After an extensive search I only found how to enable and map the the <home> and <end> keys, unfortunately not yet how to map the brightness and volume controls to the F1-F4? keys

Best Regards

You need an OS X keyboard driver for the non-typing functions to work. That applies to any keyboard.

The data all the regular keys send is the same, no matter what brand or style the keyboard is, but the volume and brightness stuff is non-standard and needs something between the keyboard and the OS to tell the OS how to deal with the inputs.

Do you know about a free driver? Or any hint how to write it?

Is there a way to declare that "something" on the defaultkeybinding.dict file?
Do you know the name of the Brightness/Volume controls? how to execute them from the command line?

Best Regards

Can't help you with that part-either writing a driver or working with the key bindings. I stopped programming a long time ago. However, Ars Technica has some help for you, and maybe that article will help you find exactly what you're looking for.
