It is difficult to use the play/pause buttons with the mouse to step through a training video, because you have to right-click in between. It would be very good if one could click on the slider to enable the stepping mode, and then use the left and right arrow keys to step forward or back through the video a few frames at a time.
Great suggestion! Thank you very much. Just added it. It's included in the next update. Then you can use the right arrow or + for going forward and left arrow or - for backwards.
