Binding to Ctrl-Shift in AutoHotKey

Question

I want to use AutoHotKey to bind a command to Ctrl+Shift, in the same way that Windows detects it in order to change text direction from right-to-left to left-to-right. That is: I want it to be invoked when Ctrl+Shift is let go, and only if no keys were pressed between pressing Ctrl+Shift and letting them go.

I bound a hotkey on ^~ Shift Up and I expected it to behave the same way as when Windows binds to it for changing the text direction. But, I found that it gets invoked even in cases where I don't want it to be invoked.

For example, I could be selecting a few words by pressing Ctrl and Shift, and then using the arrow keys. Then I let go of Ctrl and Shift and the hotkey gets invoked. I don't want this. I want a hotkey that gets invoked only if I held nothing else then Ctrl and Shift. If I use any other keys, I want the hotkey not to be invoked.

Is there a way to do this with AHK?
