If you’re not comfortable editing .ini files or your trainer doesn’t support rebinding, you can use a free tool called . This program runs in the background and translates key presses. For example, you can tell AutoHotkey: “When I press the letters U, H, J, K, treat it as if I pressed Numpad 8, 4, 5, 2.” Here’s a basic script:
Now you can enjoy spawning helicopters, changing Niko’s appearance, freezing time, and launching cars into the air all without stretching your right hand across the keyboard or reaching for a numpad that doesn’t exist. Happy modding!
The most popular trainer for GTA 4, Simple Native Trainer (usually installed as trainer.asi or snt.asi ), actually includes a built-in, though not immediately obvious, method to rebind all keys away from the numpad. The default configuration file, trainer.ini , is generated the first time you run the game with the trainer installed. Inside that .ini file, there are sections like [KeyBindings] where you can change every single control.
