The Database Switcher window provides a view which makes it easy to switch between databases or copy games between databases. The name, filter state and graphic type icon of each database is displayed, and the active database is highlighted with a yellow background.
You can open the database switcher window from the [Windows] menu, or by its shortcut key: Control+D.
To copy all the filtered games in one database to another, drag with the left mouse button from the source base to the target base. You will then see a confirmation dialog (if the target database is not the clipbase) if the games can be copied, or an error message if the games cannot be copied (for example, if a selected database is not open).
Pressing right mouse button over a database produces a popup menu applying to that database, from which you can change the database type icon or reset its filter. You can also use this menu to change the orientation of the window (to arrange the database slots vertically or horizontally) which is useful for smaller screens.
