I am using a menu from http://www.dynamicdrive.com/dynamicindex1/davidmenu.htm

However, some of my clients are complaining that it blocks information on a page (which is true). Is there anyway I can add a button which removes the side menu? This button must be createable in the ssm or ssmitems, because under no circumstances am I adding a script to EVERY single page again! It should be removeable by a keypress and created again with a different keypress. I really need this! Please help!!!
