I'm trying to speed up my workflow by making vector points move in the opposite direction simultaneously when I have two highlighted. For instance, below I highlight the top and bottom of the arrow so they will move at the same time, except I want the bottom point to come up when I'm moving the top point down. Right now, they just move up together or down together. So if point 1 is at Y:20 and point 2 is at Y:10, I want them both to go to Y:15 if I move point 1 down 5 pixels.
If the move is symmetrical.
You could also use guidelines, the grid Ctl or Cmd (') or simply using the arrow keys.
