Like Apple, Google's documentation is incredibly concise. I spent a few weeks reading Google's documentation and working with Google Docs. If I used Docs through a web browser, I could work more efficiently without fear of overwriting a collaborators changes.

You approached it like a web page, expecting to find controls with VO+Left and VO+Right, but nothing made sense.
