Magritte - how to add Submit Buttons to a form

Hello, I am using Magritte to display a standard form for my model. I have code that looks like this: form := self asComponent addValidatedForm; yourself; html render: form. This gives me a nice form with the standard 'Save' and 'Cancel' buttons. I would like to add an additional button to the form. I see that MAContainerComponent>>#addValidatedForm is where the Save and Cancel buttons are added but I cannot figure out how to add my own button so that it appears in the same div as the Save and Cancel buttons. How do I add a new button to the form? Thanks for any help you can provide, Frank
