How to send a single shift key with SendKeys?

I'm trying to automate a routine task with vbscript. It requires开发者_开发知识库 me first pressing a single shift and then input a string. How can I do that with SendKeys? If it can't be done, is there no way to automate this task without installing some new tool?

The special character for the shift key is the plus sign. Here is an article that explains further: http://www.joecolantonio.com/2011/01/21/qtp-vbscript-sendkeys-faq/
