HD Geometry Hotkey (A) not working

I’m trying to follow along with this lesson:

but the A hotkey doesn’t seem to do anything for me. I’m using the trial version. What am I doing wrong?

Have you pressed the Tool>Geometry HD>Divide HD button? After doing that you need to hold your cursor over the model before pressing the ‘A’ key.

Thanks, I had missed the step to DivideHD.
