I'm not currently aware of a way to copy nodes between animation timelines? This is useful if you are trying to 'tie' the end and beginning of two separate sequences together, or merge them.
This can be done now. See the attached video
Open 2 3D windows
Left click in 1st 3D window to make it active
select Animation that you want to copy camera node from
select and right click on the camera keyframe you want to copy>Snap to Viewpoint
Left click in 2nd 3D window to make it active
select Animation that you want to apply the camera node to - any saved camera angle in the 2nd animation will be applied to the 2nd 3D window, leaving the 1st 3D window still set to the camera angle you want to copy
Left click in the 1st 3D window again to make it active
Select and right click on the camera node you want to update>Use Current Viewpoint
We can also consider adding Copy/Paste commands in the future to the Animation Editor menu to save a few clicks

OK thats great thanks.
Perhaps its a refinement then, I was thinking 'Right click on node > Copy Node > Switch to other animation timeline > Paste node'
