Working through cascading menus

As you know, the Start-Programs menu can have many levels. For example, you may choose Start, Programs, Accessories, Entertainment before you get to the last level of menus where you can choose a particular application, such as CD Player. When you want to back up to a previous level, you can just move your mouse back to the previous level and make another choice, or you can press the Esc key to have the last level disappear from your screen.
