Navigating with mouse has it's problem too: the connected nodes should 
still be selectable before moving, if there are more nodes than the view 
can show clearly. Click to select, another to move? Scrollwheel to move 
selection, left click to move? Drag to move selection, click to move?

One option is reverting back to the idea of two scroll controls: one for 
left, one for right side. The sides could still scroll at the 
same time, or it could be better if they didn't.

1. Selection is only on one side at a time: if it's on left, pressing left 
moves and pressing right switches selection to right. Meaning of up and 
down keys depends on selection side.

2. Selection is on both sides, and we assign corners of an arrow set 
(numpad, joystick, "qezc" etc.) to intuitively work as clockwise and 
counter-clockwise.
