VoiceOver in Device Hub

When I toggle on VoiceOver in Device Hub, it looks very promising! But how can I emulate the gestures, double tap to activate, etc... Is this not possible? Right now I can just focus on different elements by clicking on them with the mouse. But, again, I can't activate anything, press button etc.
