Premier Elements 2020 Quick View Zoom Timeline

I recently upgraded from Premier Elements 2016 to the 2020 version. I am trying to do some very simple in Quick View that has seemed to change in this new version. I have added a video from a file. It is showing on the timeline, occupying about 10% of the horizontal length of the screen. I need to zoom way in on this clip to do editing. The help for Quick View arranging clips says: "To zoom in or out as you add a clip, drag the clip to the Quick view timeline. Hold down the mouse button, and press the Equals (=) key to increase the zoom factor or press the Minus (–) key to decrease it.". This is not working. Nothing changes in the view. The help also says "To zoom in on the Quick view timeline, drag the Zoom slider to the right, or click the Zoom In button". Where is the zoom slider? I cannot find this either. Any advice  here would be greatly appreciated.
