FINALLY!

So I had a minor (actually kinda major) problem with the original version. It had MAJOR delay! It was honestly very irritating.
To fix this I reduced the unecessary delays by reducing the key-down/key-up timing from 40 miliseconds to 15 miliseconds, and the response-file polling interval was reduced from 100 miliseconds to 25. This made it faster yes, but After Effects was still waiting synchronously :(
I made the script create a temporary PowerShell script and a hidden VBScript launcher. The VBScript uses WScript.Shell.Run with style 0 and the False wait parameter. I did a little more but I don’t want to bore you :D

Anyways if anyone read to the end, I hope you guys have a great day and that someone can actually find this useful.
