Selecting Multiple Items on a Timeline

I have a fairly long slide, which includes many objects and cue points, some that have triggers on them and others that have objects aligned with them. I want to select all the objects on the timeline so I can copy them to another slide. When I select the first and last object while holding down the shift key, SL copies all the objects but not the cue points for some reason. 

Is there a way to copy the whole timeline including the cue points?

 

Thanks
