Change the dictation keyboard shortcut in Preferences in Mac

Change the dictation keyboard shortcut in Preferences

You have always been able to command a Mac with your voice, but this feature has been significantly enhanced in Mountain Lion.  Now your Mac will take dictation anywhere you can type.  The preference name has changed from Speech to Dictation & Speech in the System preferences.  Here you can choose which keyboard shortcut to use to enable dictation anywhere you can normally type.  The default when dictation is on is to press the Function (Fn) key twice.  Wondering what happened to the old speech commands in Mountain Lion?  They are still there, they just moved into the redesigned Accessibility preferences under the heading Speakable Items.
