Line 4: On this line we add an id attribute with a value of "eddies". We do this so we can target that particular element with JavaScript later on.

Line 13: On this line we create a an anchor tag and denote the onmousedown event to fire a hide_menu case in the ajaxManager() function. You will note that there is no need to use a parent object as in parent.ajaxManager('hide_menu') which would be the case if were to use frames. When the xml document is imported and fully loaded into the main interface it acts as it were part of the interface itself. Take note of that as it will save a lot of headaches later on.

As you may have noticed we are pointing to a case in a JavaScript function, so let us look at that.
