You can always just assign a custom shortcut: Edit => Keyboard Shortcuts => Menu Commands => Object => Align => Horizontal Align Center and/or Vertical Align Center which I have mapped to [option+command+F] and [option+command+V] which are easily pressed one after the other to quickly align one object to another object.
