Keyboard differences between Windows and Macs

Over the years, I learned about many gotchas and strange differences between keyboard handling on Mac and Windows - pertinent especially to web apps, which use the same codebase to cater to both. I thought it might be helpful to someone if I compile them all in one place.

I knew most of these, but it's still nice to have such a reference at hand when needed.
