The F3 button on my rMBP has a figure which shows 3 rectangles, pressing the button without the FN key initiates the Expose function. I want to modify that key for another function. However I cannot directly modify it via preferences because pressing that button does not register as a specific keyboard shortcut.

Go to System Preferences -> Keyboard -> Keyboard Shortcuts. Then, on the left side, select Exposé & Spaces. On the right side you will see the current keyboard shortcuts for Exposé and Spaces. If you double click on the shortcut command (literally double click ^1 for instance) you will be able to change this to whatever you want. Just do the key-combo you want to use.
So, once you double-click on the shortcut, it'll show it as editable. Then, press the keys you want the short cut to be, all at once, for instance press Apple and J at the same time, and it'll change the shortcut.
If I open "Expose & Spaces" preference panel, I see an option to select the "fn" key to different Expose actions. This is on 10.6.

You could also change it to a normal F-key with FunctionFlip.
If anyone else is looking for a way to change it with KeyRemap4MacBook, just create a private.xml like this:
The keycode constants are defined in src/bridge/generator/keycode/data. The test folder has a checkbox.xml with all the predefined mappings.
