There is two ways to use these hotkeys for for different game configs.
you can set saperate configs for different games, when you want to switch to another game, you will just need to press the corresponding hotkey.or you can set several configs for one game, for example, config 1 for infantry, config 2 for tank operation, config 3 for jet.
In this way, you can set completely different keymappings for different
combat modes, and different HIP/ADS sensitivity for varied vehicles.
and switch to the config you need just in game!
