The what? And the user is supposed to know this?
I'm only saying the keyword is wrong. It isn't the camera angle.

Based on what you write I am not sure you understood that there is no need
to have an order for the keywords, only an order in which they take effect.

Do you mean something like:

Camera
    	Type
    	if perspective
    	    	(right, direction) or angle
    	    	sky
    	    	...
    	if orthographic
    	    	...
    	    	...
    	type independent identifiers

I always thought that it was because the order directly influenced
the order of transformations of the camera ray.  Isn't it ?

Oh, OK.  Let me say :

1) projection mode
2) location and look_at
3) sky
4) right and up
5) angle or direction
