I have found that once u press 2 fingers down it takes a few seconds but the box around keyboard will turn blue and you can move it. Also the only time I can move it is if the cursor is in a blank field. If I type anything it won't let me move keyboard. It would b nice if this was fixed to be a Lil more fluid in any future updates.
Pinch and squeeze 2 fingers together on top of the keyboard to get the options menu for the keyboard. You will have 3 options - QWERTY, Floating or Split.
