ReWASD key simulation method?

[alansete]

So I've always wanted to develop my own software for key remapping and macro functions to learn new things about programming, nevertheless, never managed to fully understood how to do one. Came here from a google search result related to different methods to simulate key presses and hence key sequencing done by software like ReWASD. I tried to do my search over the whole project to see if I could find which method uses for macros and remapping for it to be safe to use in certain games but couldn't really find an answer to it. I was wondering if any of you could give me a hint about it.

This is not a complete rewasd dump, there is also a driver (which emulates the gamepad) and a service that connects rewasdEngine and driver, this is if you simplify as much as possible, to develop your analogue rewasd, look towards winapi, you need knowledge mainly c++
