To make working with formulae easier, use the context menus, which can be called up with a right mouse-click. This applies especially to the Commands window. This context menu contains all the commands that are found in the Formula Elements window, and also operators, and so on, which can be inserted into your formula by mouse-click without having to key them into the Commands window.
如果希望更便捷地使用公式，可以通过单击鼠标右健调用上下文菜单。该操作尤其适用于“命令”窗口。此上下文菜单除包含“公式元素”窗口中显示的所有命令之外，还包含运算符等内容。这些命令或内容仅需要通过单击鼠标就可以插入到公式中，而无需在“命令”窗口中键入。
