其使用格式为：object.SendKeysstring

“object”：表示WshShell对象
“string”：表示要发送的按键指令字符串，需要放在英文双引号中。

1.基本键

　　一般来说，要发送的按键指令都可以直接用该按键字符本身来表示，例如要发送字母“x”，使用“WshShell.SendKeys"x"”即可。当然，也可直接发送多个按键指令，只需要将按键字符按顺序排列在一起即可，例如，要发送按键“happy”，可以使用“WshShell.SendKeys"happy"”。

2.特殊功能键

　　对于需要与Shift、Ctrl、Alt三个控制键组合的按键，SendKeys使用特殊字符来表示：

Shift---------WshShell.SendKeys"+"
Ctrl---------WshShell.SendKeys"^"
Alt---------WshShell.SendKeys"%"

由于“+”、“^”这些字符用来表示特殊的控制按键了，如何表示这些按键呢？

只要用大括号括住这些字符即可。例如:

要发送加号“+”，可使用“WshShell.SendKeys"{+}"”

另外对于一些不会生成字符的控制功能按键，也同样需要使用大括号括起来按键的名称，例如要发送回车键，需要用“WshShell.SendKeys"{ENTER}"”表示，发送向下的方向键用“WshShell.SendKeys"{DOWN}"”表示。

Space---------WshShell.SendKeys""
Enter---------WshShell.SendKeys"{ENTER}"
←---------WshShell.SendKeys"{RIGHT}"
↑---------WshShell.SendKeys"{UP}"
F1---------WshShell.SendKeys"{F1}"

Tips:如果需要发送多个重复的单字母按键，不必重复输入该字母，SendKeys允许使用简化格式进行描述，使用格式为“{按键数字}”。例如要发送10个字母“x”，则输入“WshShell.SendKeys"{x10}"”即可。
