It’s a little hard to understand your question, but in short, you decide what key or control does what.
Aside from the fact that Unity has a default input manager setup, Unity has no concept of a ‘forward’ key or anything like that; defining such controls is up to you. Although there’s more than one way to do it, this is commonly handled via the input manager, which allows you to create ‘virtual controls’ that the user can then map as they see fit using the ‘graphics and input’ dialog that (optionally) opens when you launch a standalone app.
Beyond that, I’d recommend reading the docs for the input manager and the input system, and then posting back with whatever specific questions you have.
Also, you don’t have to write ‘plzz’ in your posts 
We already know you’re looking for help, and writing ‘plzz’ is unlikely to make anyone more inclined to respond than they might otherwise be.
Ahh tnx and tnx again for help and sry about that (“plzz”) x)
