Use Mountain Lion's dictation feature for enqueuable programmer-defined commands.
Don't use this in a production app as of yet. It is merely here for entertainment purposes. If you're going to use it, be sure to only enqueue blocks that are associated with short, preferrably 1-word, commands. Remember that the dictation depends on OS X's ability to reason with it's servers, and this control provides no fault-checking, so any false positives or bad results are not the fault of the control.
