So, this may have been covered in the paper instructions that came with the Ipad Pro Smart Keyboard that I didn't read, but I didn't see it anywhere else, so I thought I'd post it for other befuddled users. When using the Smart Keyboard, you can hide the virtual keyboard by hitting the glob key on the bottom left twice. Took me a few minutes to figure it out, as I was used to the dedicatied keyboard key on other mobile keyboards.
