Ctrl + R in blender inserts a loop edge in a mesh. If you insert just one and left click you can slide it between two bordering edges. In 2.49 you could influence the way the added loop edge is moved by disabling the proportional mode with the P key. Now I do not know how to do it in 2.58. Either it is some other keys I need to be pressing or the utility is gone altogether.
Since I cant find any answer to my question I thought I’d ask directly so if anyone knows how to do it in 2.58 please share your knowledge.
