With this point, different default values for the input of the trains can be defined. The usage of default values has the advantage that you can search for it. With a free text input one could mistype, and the train will never be found again. The following image shows the dialog to manage the default values.

In this dialog one finds on the left side Buttons with the names of the different fields. By pressing one Button, the defined default values for this field appears. The initial values were filled, while creating the database. With some fields (e.g. era) no, or a minimum modification is necessary. Other fields (e.g. dealers) must be changed more for your usage.

For renaming an entry, one clicks on the appropriate text. Then, one can change it. If an entry is already used, all trains concerned these values are updated automatically. If one wants to add an entry, one must press the Button "Insert". A new entry with the name "New" is created. It can be renamed, as described above. To delete an entry it must be marked. Afterwards it can be deleted with the Button "Delete".

Alternatively, an entry can be administered in the corresponding popup-menu.
It is a good idea to enter only already known values. Later on, you can add new values direct in the popup-menu.
If an entry is already used, all trains concerned these values are updated automatically.
The initial values (e.g. dealer) are made for the German market. But you can change them very easy to your market.
