so while i'm idiling around and i see something i wanna mark on the sideimaging screen i simply use my arrow keys and i cursor should appear and i move it over and hit mark, ok, does it have to be in just the view of sideimaging or can it be in one of the split screens and still work the same way, i prefer to have the di/2d on two small screens and the sideimaing in the third larger screen, though that big screen down image is pretty neat.
