While disabling an action will still keep it, deleting an action will remove it completely. To delete an action:
Open the Cards
explorer to display all actions.
Right-click the action to be deleted, and select Delete. A confirmation message is displayed.
Click the OK
icon
to confirm the deletion.
If you try to delete an action and it has a dependent view, then a warning dialogue is displayed, offering you the option to cancel the delete operation.
