This code this working except the left and right arrow keys. Can someone tell me why the arrow keys not working?

<script type="text/javascript">
$(document).ready(function()
{
      $('#container').click(function()
      {
            var totalWidth = 0;
            var sizeWidth = $('#insertData1').outerWidth();
            $('#ul_a li').each(function()
            {
                  var widthS = $(this).width();
                  var textW = $(this).text();
                 
                  var widthN = parseInt(widthS,10);
                  if((totalWidth + widthN) < sizeWidth)
                  {
                        totalWidth = totalWidth + widthN;
                        $('#insertData2').append('<li>'  + textW + '</li>');                              
                  }else
                  {
                      return false;
                       
                  }
                  $('#insertData2 li').hover(function()
                  {
                            $(this).addClass('highlight');
                        $('#insertData2 li').keyup(function(e)
                        {
                              if(e.keyCode == 37)
                              {
                                    $('#insertData2 li').addClass('highlight');
                              }else if(e.keyCode == 39)
                              {
                                    $('#insertData2 li').addClass('highlight');
                              }
                                    return false;
                        });
                  }, function()
                  {
                            $(this).removeClass('highlight');
                  });
            });
      });

you are assigning the keyup event to 'insertData2 li', only when they are hovered once.
So, if you haven't yet hovered on them yet, then it means the keyup event has not binded yet.

Move your arrow key handling code outside of the hover handler of "insertData2 li"

copy this code
$('#insertData2 li').keyup(function(e)
                        {
                              if(e.keyCode == 37)
                              {
                                    $('#insertData2 li').addClass('highlight');
                              }else if(e.keyCode == 39)
                              {
                                    $('#insertData2 li').addClass('highlight');
                              }
                                    return false;
                        });

directly inside the document.ready, and outside $('#container').click

$(document).keydown(function(e){
    if (e.keyCode == 37) {
       alert( "left pressed" );
       return false;
    }
});

I put the keycode outside the container code as suggested but still not highlighting. The hover code is still working.

$(document).ready(function()
{
      $('#container').click(function()
      {
            var totalWidth = 0;
            var sizeWidth = $('#insertData1').outerWidth();
            $('#ul_a li').each(function()
            {
                  var widthS = $(this).width();
                  var textW = $(this).text();
                 
                  var widthN = parseInt(widthS,10);
                  if((totalWidth + widthN) < sizeWidth)
                  {
                        totalWidth = totalWidth + widthN;
                        $('#insertData2').append('<li>'  + textW + '</li>');                              
                  }else
                  {
                      return false;
                       
                  }
                  $('#insertData2 li').hover(function()
                  {
                            $(this).addClass('highlight');
                  }, function()
                  {
                            $(this).removeClass('highlight');
                  });
            });
      });
      $('#insertData2 li').keyup(function(e)
      {
            if(e.keyCode == 37)
            {
                  $('#insertData2 li').addClass('highlight');
            }else if(e.keyCode == 39)
            {
                  $('#insertData2 li').addClass('highlight');
            }
                  return false;
      });

Still does not work. I even tried putting it into a separate document.ready. The hover code is still working.

<script type="text/javascript">
$(document).ready(function()
{
      $('#container').click(function()
      {
            var totalWidth = 0;
            var sizeWidth = $('#insertData1').outerWidth();
            $('#ul_a li').each(function()
            {
                  var widthS = $(this).width();
                  var textW = $(this).text();
                 
                  var widthN = parseInt(widthS,10);
                  if((totalWidth + widthN) < sizeWidth)
                  {
                        totalWidth = totalWidth + widthN;
                        $('#insertData2').append('<li>'  + textW + '</li>');                              
                  }else
                  {
                      return false;
                       
                  }
                  $('#insertData2 li').hover(function()
                  {
                            $(this).addClass('highlight');
                  }, function()
                  {
                            $(this).removeClass('highlight');
                  });
            });
      });
});
</script>
<script type="text/javascript">
$(document).ready(function()
{
      $('#insertData2 li').keyup(function(e)
      {
            if(e.keyCode == 37)
            {
                 $('#insertData2 li').addClass('highlight');
            }else if(e.keyCode == 39)
            {
                  $('#insertData2 li').addClass('highlight');
            }
                  return false;
      });      
});
