In this case a BooleanWritable’s default trueText facet is true—to modify you simply click to select, then type over with whatever text is needed. For example, change true to On and false to Off. When done click OK and then Save to make the actual point change.
Optionally, in addition to modifying existing facets, you can add or remove facet values in a point. On many points you may only modify or provide new values for default facets. In the case of writable points, you can add a facet to limit override duration.
