I wanted to post this in case others want to be able to rotate while moving without having to open the F3 dialog and peck around for the rotate buttons, or to have to search for the rotate button in the menu toolbar.
Put the following line in your .cdsinit file (usually at the root dfii folder of your design or your home folder). Then execute load(".cdsinit") in the CIW.
It assigns key 8 and Ctrl-r to rotate left 90 deg. It overwrites the default redraw for Ctrl-r, which I never need to use.
hiSetBindKey("Layout" "<Key>8" "_leRotateOrFlip(\"R90\")") ;;rotate left 90 deg leEditToolbarRotateLeft
hiSetBindKey("Layout" "Ctrl<Key>r" "_leRotateOrFlip(\"R90\")") ;;rotate left 90 deg leEditToolbarRotateLeft
