[ylussaud]

That shortcut should be enable on modules, templates, and queries to generate the documentation. We can use CTLR+J like the JDT.

• Module

[**
 * The documentation of the module <module name>.
 * @author <user>
 * @version <version>
 * @since <version>
 */]

• Template and Query

[**
 * The documentation of the template generate.
 * @param <parameter name>
 * @param <parameter name>
 * @param <parameter name>
