Hi I have read it...

I still do not understand.

Somebody told me to do this but I do not know if it will work:

if (selectorHX != selectorPOS){
  delay (100);}
  if (selectorPOS == LOW){ // If switch is in the 'one' position
    Keyboard.press(KEY_LEFT_ARROW);
    delay (100);
    Keyboard.releaseAll();
    selectorHX = selectorPOS;}
  else{
    Keyboard.press(KEY_RIGHT_ARROW); // If switch is in the 'two' position
    delay (100);
    Keyboard.releaseAll();
    selectorHX = selectorPOS;}
