Looking for simple forward jump hotkey/macro

[straightup2lazy]

I want to be able to do a perfect forward jump from standing still position to help with wall jumping. I tried messing around with autohotkey but even though I can send w and space at the same time (tested in notepad), it doesn't give the desired result ingame (just makes me auto walk forward , doesn't even jump aside from a few rare occasions were it did work but usually it just makes me run forward until I cancel it by pressing forward myself)

Anyways I was hoping someone here has a script to forward jump perfectly that they would like to share or give me some advice on how to tackle this problem. That would be very much appreciated. Thank you.

Why dont you use a razer mouse? It allows doing macros that work very finely.
