Changing the viewpoint angle

[jaytee]

The world I'm creating needs to use the arrow keys to control the view. I am starting with the arrow key control from the gallery example:

#Go Forward or Backward
if viz.iskeydown(viz.KEY_UP):
   viz.move(0,0,TRANSLATE_INC)
elif viz.iskeydown(viz.KEY_DOWN):
   viz.move(0,0,-TRANSLATE_INC)
			
#Turn Left or Right
if viz.iskeydown(viz.KEY_LEFT):
   viz.rotate(viz.BODY_ORI,-ROTATION_INC,0,0)
elif viz.iskeydown(viz.KEY_RIGHT):
   viz.rotate(viz.BODY_ORI,ROTATION_INC,0,0)

How would I modify this so that the up and down arrows instead control the view pitch? (not sure if that's the correct terminology... I want to change how high or low the user is looking).

Thanks so much for your help... sorry for all these newbie questions.
