--- this part moves a sprite based on what arrow key a person has typed
-- the subroutine  'keyhandlerarrow' checks for which arrow is pressed
-- the example moves sprite 4 based on the arrows
-- the case part is a more elegant way of calling subroutines based on arrow
-- you would have to write the routines 'turnleft' etc 
-- you would attach this to a frame script in the score
