How does one edit an animation path to change the view angle at the various points along the path? My animation walks me through the house but the camera is always pointed in the same direction, which isn't always "forward".

Well my problem is that controlling the "little man" in the walk-thru mode using the mouse is a challenge - he does a lot of stumbling around, walking through walls, etc. So instead I set the animation path precisely by clicking along the path in 2D mode, but the problem with that is that while the 2D view displays the camera angle at each point along the path, I can't figure out how to rotate it. The entire trip through the structure has the camera facing, for example, northeast, when I want it to face forward even as the path changes direction.
