Mostrar  y esconder div al hacer scroll  con jquery y debounce








 //Esto en tu Scripts

$(window).scroll($.debounce( 250, true, function(){
//cuando haces scroll  
 $('#header').show();

} ) );
$(window).scroll($.debounce( 5000, function(){
//cuando esta en pausa
    $('#header').hide();

} ) );




Esta parte en un nuevo archivo js



(function(window,undefined){
  '$:nomunge';

  var $ = window.jQuery || window.Cowboy || ( window.Cowboy = {} ),
   
    jq_throttle;

 
  $.throttle = jq_throttle = function( delay, no_trailing, callback, debounce_mode ) {

    var timeout_id,

      last_exec = 0;

    if ( typeof no_trailing !== 'boolean' ) {
      debounce_mode = callback;
      callback = no_trailing;
      no_trailing = undefined;
    }

    function wrapper() {
      var that = this,

        args = arguments;
