how to use puppeteer?

HI,
I tried to follow the tutorial "DAZ 3D - DAZ Studio Animation Tutorial Part 2 " on Youtube, it is a good tutorial about using the puppeteer, however, when I do it on my DS 4 Pro, don't understand why, it does not do anything while I am in the Preview mode, just can't switch among the different poses I put in the grids. Am I missing anything? or any tool needed ?

It's okay to post links to videos on Youtube. Part 2
The only tool being used is the mouse. Click on a pose and drag the mouse around from pose to pose. The figure moves accordingly.
This video is also helpful even though it's for an older edition of D/S.

If you open the DAZ Studio timeline the motions are saved to it as a animation from Puppeteer if you do record.
