(This Help panel can be dragged to any convenient position.)
When you enter the Gallery the initial screen shows a thumbnail for each available video.
Clicking/tapping a thumbnail will open the main viewer - click the little left arrow at lower left to start the video (it may be in the middle on a touch device). Click the arrows to the left and right of the video to scroll through all the videos or, on a touch screen, swipe the videos left and right.

The 2 buttons at top right of window will enlarge the window to full screen (not on touch devices) and close the viewer.

If the control buttons disappear, just move the mouse or tap on the screen edge to bring them back.
