Using menus

Progress supports both menu bars and pop-up menus. A menu bar is a horizontal bar displayed at the top of a window. The menu bar can contain submenus you can drop down to select individual items. A pop-up menu is a list of menu items associated with an individual visual object in a window. Normally, you invoke a pop-up menu by clicking the right mouse key on the object it’s associated with.
