Pressing buttons on a game in the background

[NoTalker]

Hello I'm new, Id like to Make a script for a game I'm playing that allows us to use two accounts.

My other account would be playing with me in the background and I'd like make a script so when I press a button like f9 or something the game in the background presses left control and M to drop their points and then G to ready up for the next round without me having to alt tab back and forth between accounts.

Any help would be appreciated, thanks

Oh I'm using sandboxie to run the other account idk if that matter so I thought I'd add it.

No idea if I should be using ahk version 1 or 2

It is best to use v2 when writing new code.
