When a window has a menu line with one or more choices, the window will have pulldown menus. By using these, the user may activate commands. When only the term menu is used in this manual, a pulldown menu is meant. If the command in the pulldown menu has three dots after the title, the command will open a window. Otherwise, a command will be executed directly. If one letter is underlined in the menu title, the menu can be opened with an keyboard shortcut.
