Rotating components in routing

I know when you first put in items like T's, valves, etc. in a route you can press tab and rotate them, but it only rotates in a few positions. Is there a way you can just rotate the part in 90 degree intervals? I realize you can also move it with the triad, but I always find when I do that my pipes don't end up straight. :/ Thanks for any help.
