I am currently hiding my dock. I would like to unhide it whenever a the fn key is pressed. Is this possible?

You can assign that fn to show/hide dock in Keyboard shortcuts, but you will override the original fn key.

Or you can create a Service in Automator that act upon a keystroke

use this action pack to act upon key and do what you want building up your workflow.

That's not going to work with the fn key. –  ghoppe Sep 24 '10 at 7:04
    
nop, but you can assign other that does everything –  balexandre Sep 24 '10 at 8:12
    
That action pack allows you to type a keystroke, not use a keystroke to activate an automator action –  Casebash Sep 25 '10 at 10:40

The fn key is a modifier key that lets you use a software function key F1-F19 when held down, instead of the built-in hardware F key functions (brightness, volume, etc.)

So it's not possible to use that particular key on its own as a keyboard shortcut, just as it's not possible to use the shift key on its own.

The best you can do is set the shortcut to F13 using System Preferences > Keyboard > Keyboard shortcuts, which on my particular keyboard is just above the fn key…
