I see here are the masters of ahk!
Is there a smart way to mark/record from a specific moment till "done" and just reply it 1/n times? I tried many macro tools but none of them was "just easy" to use.
Have you looked into something like this[1] for generating the macro as an ahk file? Full disclosure: I have not used it, but it seems like what you’re looking for. If you find that it suits your needs, I’d use that to record the macro and then wrap it in a loop from 1..N where N is based on the Fn key you press. That should do the trick unless I’m misunderstanding.
I wish I could be of more help, but this repo seems like a decent starting point for your use case.
Apologies if the formatting is poor as I am on mobile.
