how to: make pipe run up and down?

[junkriffs™]

what the button to rotate R works but only rotates L and R. not up and down. if that makes sense. like for the Elbow pipe i can get it to turn to go left or right but i cant get it to let me go up or down. same for the T-pipe. any hints? thx for info

Try T and Y (or Z depending on your keyboard).
