Where is hyphenation ON/OFF box in keyboard shorcuts?

Sorry for this basic question, but I want to assign a keyboard shortcut to the hyphenation checkbox (or the equivalent function). In other words, I want to be able to press a keyboard shortcut that turns off hyphenation in a given paragraph, which is the function of this checkbox that usually sits in the text control panel at the top of the screen when viewing in paragraph view. Screen shot here:

But I can't seem to figure out what this is called or where it exists in the customize keyboard shortcut options.

Thanks...I'm still using CS5, but I'm hoping that anyone using CC will know (or it hasn't changed in CC).
