Tooltip Widget Trigger

Hi. I'm currently working with an Adobe Muse Tooltip widget and need the triggers to be invisible - as I want these to be large hotspots that click through to other pages.

There appear to be two states to each trigger. I can select trigger's active indicator and change it's shape and fill it with none. However I cannot workout how to select the second shape - which appears when another trigger is active - and change its colour.

I'm sure it's a simple process - but even in the Trigger & Target video (see 07.00) - http://tv.adobe.com/watch/csinsider-design/muse-trigger-target/ this subject it isn't really explained that well.

Any advice or assistance would be gratefully received.
