<font color="#F97316">**IMPORTANT**</font>**:&#x20;**&#x4F;nly advanced DairyComp users should use the ALTER command to edit system settings. We highly recommend reviewing the cautions in [ALTER Overview](docId:1MW1mvF3HJ2V-u2QoXzl0) before proceeding.
:::

Follow the steps below to edit the events to include in a combo event for a vet list:

1. In the command line, enter `ALTER\9` to view your user-defined events.
   The ALTER9 : Events window opens, showing all event types configured for DairyComp.
