How do I add default shortcuts for SystemActions (like cut, paste, etc)?
You just need to include the defaults module org.netbeans.modules.defaults that defines the key bindings for the system actions.
For Maven, add the following dependency to your app:
<dependency>
<groupId>org.netbeans.modules</groupId>
<artifactId>org-netbeans-modules-defaults</artifactId>
<version>${netbeans.version}</version>
</dependency>
