Swapping the Alt and Command Keys

Rather than install additional software on my Mac to re-map the keys and risk system resources and potential conflicts, I found this functionality was already available, but buried in the Mac's System Preferences. I found the answer in System Preferences > Keyboard > Modifier Keys:


If I ever switch keyboards and need to change back, it's a simple as restoring defaults.
