How many of these Google Now commands do you know

If you recall, my favourite feature since Jellybean has been Google Now... and it's only gotten better over the years.

Now, with the improvements there's been more and more commands that Majel has learned to respond to.  If you've been keeping up with my database page you'll have seen the list I've been keeping - but if you don't like a simple Word document, Google has launched a new page to show you what it has in store for you when you say "Ok Google".

How many of them did you know of?
