You can press and hold the 1 , 2 , 3 , or 4 keys to select from one of four directions:
forward, backward, rotate right, rotate left. These directions also work with the CH+ , CH- ,
VOL+ , and VOL- keys, which works nicely because those buttons point in the forward,
backward, right, and left directions on most remotes.
