Changing the viewpoint angle

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:

Code:
#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.

the 3 arguments to the viz.rotate command is yaw, pitch, and roll. So just make ROTATION_INC the second argument instead of the first.
Code:
#Turn Up or Down
if viz.iskeydown(viz.KEY_UP):
   viz.rotate(viz.BODY_ORI,0,-ROTATION_INC,0)
elif viz.iskeydown(viz.KEY_DOWN):
   viz.rotate(viz.BODY_ORI,0,ROTATION_INC,0)
