The Custom function enables the user either to compose a new combination of Event and Acton not available under the predefined list of functions or to create a group command to allow the execution of sequential commands.
To create a custom function:
1. From the Edit Rule window, choose Custom Function from the drop-down menu in the Function field.
2. In the Parameters pane, select the appropriate event and the action to be executed for that event.
3. To configure a Group command, select Group Command from the Command Type drop-down menu.
The Parameters pane enables the user to add actions to the Group.
4. You can define another set of Group commands and specify whether these commands should be executed sequentially or in parallel.
5. You can use Custom Function to configure an event that triggers an executable by selecting the action Run an Executable.
