ChessBase has two main methods for accessing a database. On the one hand the search mask offers you a flexible method of searching by various criteria; on the other the keys (openings, players, etc.) give you a structured means of access which has the additional advantage of being virtually instantaneous.
The theme key of ChessBase combines both methods. A key is defined by the contents of the search mask, and this definition is permanently stored with the key.
The classification keys for themes, strategy, tactics and endgames can all be viewed by clicking tabs in the list window.
If you load a game from a theme key the program will jump to the position that led to the match (if that is possible).
