Using Tear-Off Menus
In some applications such as Mailer and Calendar, you can "tear off" a menu, which keeps it open on your desktop for repeated use. You can recognize the availability of a tear-off menu by the appearance of a dotted line at the top of the menu.
To Keep a Tear-Off Menu on the Desktop
Display the menu by clicking its name in the menu bar.
Click the dotted line above the first menu item.
The tear-off menu stays on your desktop until you dismiss it by either pressing Alt+F4 or double-clicking the Window menu button (in the upper left corner of the application's window).
