When you open a sheet in the client area, you can display the title of the window (sheet) in a list at the end of any of the menu bar drop-down menus.  For example, this menu lists one open sheet.

TIP:   To display the sheet titles, specify the number of the menu item in which you want them listed when you call the OpenSheet function to open each sheet.

If more than nine sheets are open at one time, the first nine sheets are listed in the menu and More Windows displays in the in the tenth position. When you click More Windows, the Select Window list box displays a list of open sheets and you can select the sheet you want to activate.
