Define an action in File >> New for the new item

Modify the creatables.conf file to define the new item in File >> New.

1. Open the creatables.conf file in your template directory.
2. Notice that the Category elements organize the creatables into groups. Find the Category element with a name attribute of Database. Modify the File element to represent the newly defined database file by changing the label, extension, and source attributes.

   <Category index="30" label="Database" name="Database">
     <File index="30" name="DBXNewERD" 
       action="DBOpen" 
       label="DB Schema (.4dbz)" 
       description="Create a new DB schema" 
       icon="document_newSchema" 
       extension="4dbz"  
       source="creatables/dbapp.4dbz" 
       isTemplate="true"/>
   </Category>

3. Save the changes.
4. Since the source element was changed to creatables/dbapp.4dbz, create that file in the creatables subdirectory in your template directory. Copy and rename dbapp.4dbx to dbapp.4dbz.
