Show/Hide Ribbon by clicking a Web Part or by using jQuery

I am trying to hide the ribbon by default, but display the ribbon when a user gives focus (clicking) on any web part on a page. There are several sites I have tried to emulate, however, have run into a snag during the implementation. The sites I have found helpful, include:

The option I am currently working with most is the 2nd choice which utilizes the keyboard keys CTRL-G to show/hide the ribbon. While this is a good solution, it does not address a critical element which is to show the ribbon when a web part is clicked or receives focus. How can I do this?

Here is the current code to register the CTRL-G keys

// Registering 'ctrl' + 'G' button press
$.ctrl('G', function (s) {
    var ribbonElement = $(CtrlGControlsToHide);
    var displayPropValue = (ribbonElement.css('display') == 'none' ? 'block' : 'none');
    ribbonElement.css('display', displayPropValue);
    // Set display state for the following hour
    var date = new Date();
    date.setTime(date.getTime() + (60 * 60 * 1000));
    $.cookie(RibbonDisplayCookieName, displayPropValue, { expires: date });

}, ["Control G pressed"]);

// Loading cookie value of ribbon display
if ($.cookie(RibbonDisplayCookieName) == 'block')
    document.write("<style> " + CtrlGControlsToHide + " { display:block; } </style>");

Here is my attempt to show/hide the ribbon when a web part is clicked. Something is wrong with my code below.

                

function OnRibbonMinimizedChanged(ribbonMinimized)
 {ULSxSy:;
  var ribbonElement=GetCachedElement("s4-ribbonrow");
  if (ribbonElement)
  {
    if (ribbonMinimized)
    {
        ribbonElement.style.display = "none";
        //alert('None');
        //$(".mysidenav").animate({ 'margin-top': '15px' }, 0);
    }
    else
    {
        ribbonElement.style.display = "block";
        //alert('Block');
    }
   }
  }
