How can I create a keyboard shortcut for LaunchPad on OS X Lion (10.7)? I know how to open Launchpad via a gesture, creating a hot corner and obviously clicking on it in the dock .... what I am looking for is creating a keyboard shortcut to open Launchpad. I tried going to System Preferences | Keyboard | Keyboard Shortcuts | Launchpad &amp; Dock, but I cannot add any shortcut for the "Show Launchpad" checkbox that is there.

Has anyone figured out how to add a keyboard shortcut? I believe that would make Launchpad infinitely useful.
You can also set a shortcut of your choosing by adjusting Lion's built-in keyboard preferences. If you go to System Preferences --> Keyboard, one of the settings menus on the left side bar is for Launchpad &amp; Dock. 

Make sure the check box next to 'Show Launchpad' is selected, then double click to the right under the listed shortcut to turn dock hiding on/off. You'll see a data entry box selected, and you can then enter whatever shortcut you'd like.
