Description:	This function tests if a keyboard shortcut was attempted
				(checks for the Ctrl+Shift combination) then it loops
				through all of the form elements on the page, looking for
				either a shortcutkey attribute or a shortcutkeycode attribute
				on each element. When one is found it is compared to the
				key that was pressed with the Ctrl+Shift combination. If
				a match is found, then it will set the focus to that element
				and if the element is a button, it will invoke the click event.
