  I suspect that this is due to the fact that, on a Mac, the option key cannot be used by itself to fire a command. All "normal" keyboard shortcuts on a Mac must involve at least one of the Command or Control keys. There are apparent exceptions to this rule, but they are all either special functions of the operating system (such as accented characters) or specially programmed features in particular applications (such as using unmodified keys to access tools in various drawing programs).
