I have a 2013 MacBook Pro Retina 15" and I'm trying to set the function keys to perform as normal function keys. So I want the behaviour to be inverted from the standard behaviour where I need to press Fn to get the keys to work normally. I've enabled the setting in Preferences as shown below.

Preferences Pane

This works fine for all function keys except F11 and F12.

Fn + F11 and Fn + F12 both have the expected behaviour of adjusting the volume now, but when I press F11 by itself it enters Expose and when I press F12 by itself it launches Dashboard.

How can I get my F11 and F12 keys to just behave like normal function keys?

Well I actually just figured this out. In Preferences under Mission Control there are two options that must be set to blank shown in the screenshot below.

In OS X 10.9 Mavericks (and possibly earlier too), the same setting can also be changed from Keyboard, Shortcuts, in the Mission Control section there. –  Arjan Aug 15 '14 at 21:10
