When using the Source: Database in Opening Explorer you are presented with the moves and statistics from the database for the current position (whatever that is).
One of of the powerful features of Opening Explorer is the ability to apply a real-time game filter based on the current position. By clicking the Show games button you can immediately set the filter and games listed in the Game Explorer pane to only show the games which have this position in them. Therefore simply by clicking the Show games button you will then have a game list of all the games that contributed to the moves and statistics shown.
To make the game filter be applied automatically each time you go to a new position in the Game Notation select the "Automatically set filter" checkbox. With that set the game list will update automatically in real-time to show only the games which reach the current position. With the filer set automatically the Show games button will no longer be required so will not be displayed.
