How can I disable my pop-up button?

Is it possible to disable the Command-Control-D word definition popup in OS X Lion?

• Mac OS X Lion introduced a new feature where in many applications you can press Command-Control-D to produce a popup with the definition for the word under the mouse cursor. A side effect of this is that you can no longer use the same shortcut to access functionality in other applications (for example, Emacs). Is it possible to either a) disable the word definition Command-Control-D keyboard shortcut, or b) change the word definition keyboard shortcut to something other than Command-Control-D?

• Answer:

  You can definitely change and disable this setting. If you go to The Keyboard preference pane in system preferences and then to the Keyboard Shortcuts tab you have more options that most people realize. Defining something in the dictionary is under the "Services" Level of that preference pane. Either click the checkbox to turn it off or change the keyboard shortcut to something you like, or even 'none'.
