Set brackets were previously inserted in the Formula Elements window or directly in the Commands window as &quot; left lbrace < ? > right rbrace &quot; . Now, a left and a right set bracket can also be inserted using &quot; lbrace &quot; and &quot; rbrace &quot; , with or without wildcards.
一对括号以前是在“公式元素”窗口中插入的或是直接在“命令”窗口中输入 &quot; left lbrace < ? > right rbrace &quot; 插入的。现在，还可以使用 &quot; lbrace &quot; 和 &quot; rbrace &quot; （带或不带通配符）分别插入左括号和右括号。
