其使用格式为：object.SendKeys string
“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 "{x 10}"”即可。
