When you click the Start button, a pop-up menu (the Start menu) appears. The Start menu shows all of the applications that are on your computer. It also lists several options, including Shutdown, Help, Find, and Programs.
If you select Programs, a pop-up menu appears. Pop-up menus like this are called cascading menus. If a cascading menu is available, a small black triangle appears next to the name of the application or function.
