I am spending way more energy on this thread than is healthy :D

But I can understand where you're coming from, I am just very frustrated that this user-interface-design-genius trillion dollar company can not change the input mechanism of one of their most used product from the:

a b c d e [f] g h i j k etc... Backspace

model with only <-> movement and no way to make an input correction other than backspace, to something like:

  a b  c  d  Backspace
  e f [g] h  forward 
  i j  k  l  backward
  m n  o  p

Which is the way almost all other TV-centered apps I use function and works much better.
