How do I rotate a group of vertices without deforming its shape? Does anybody know the hotkey combination to rotate a group of vertices 45° in edit mode without deforming the cylinder shape? I forgot this important tool, I remember that I could constrain the axes with the Alt key.



BTW see below the screen shot to understand better what I would like to achieve:
Its called Shear and is accessible through the hotkey &#8679; Shift&#9096; Ctrl&#9095; AltS or the menu entry
Object/Mesh/Curve/Surface ‣ Transform ‣ Shear
