You
            can clear or reset several Colour Warper values in the Basics menu
            using individual C/R boxes. C resets the value for the current frame
            by setting a keyframe. R resets the value for the entire animation
            curve.
         
         To reset a Colour Warper value:
         
         
            - In the Basics menu, do one of the following:
               
                  - Select C from the C/R box next to a control.
                  
 The value is reset at
                  the current frame.
                
                  - Select R from the C/R box.
                  
 The value is reset for
                  the entire animation curve.
                NoteFields that do not
                     have C/R boxes next to them cannot be reset. Use the Undo box instead.
