It's the same as basic object interaction. Create a scene object. Setup the interaction position & alignment via the objects properties tab. Next create the object area (interaction polygon) that will be used to detect when the mouse cursor enters the objects interaction area. Now create a x command executed at destination action & create a change scene action part, select the active character from the dropdown list & define the scene you will be changing to & the object to set the characters position in the next scene to. For double click: create a double click action (immediate) & add the same action(s) you created in the x command executed at destination action.
Hope this helps.
P.S: you could try downloading one of the demo templates off the main page. I'm sure they will give you a better understanding of what I just said (above).
