How to manipulate the web page backstage?

[zhuoluo]

I want to know how to manipulate a web page in the background, so I can control several pages at the same time, perform in the background, click, and play games at the same time.

I wonder if there is any way?

You can ControlSend to window in the background that isn't minimized.
For example You can replicate Your ordinary click (like in excel) to clicker game in browser window that stay in the background.

I think you can use comobjcreate to use IE and manipulate the web page by elementID
