 Toggles window chrome for your browser.         
 Makes the window almost chromeless meaning no titlebar         
 but taskbar should still be accessible.         

 Convenient for going fullscreen without losing all         
 those useful toolbars and the windows taskbar.        

 By default this button makes the browser startup chromeless         
 you can change this by commenting out the appropriately marked         
 line of code in the button's initialization tab.         

********************************************************************        

 Directly Clicking on the Button does the following:        

     L = Toggles Chrome         
     Any Other Click = Custom Buttons Context Menu
