Create multiple keyboards/mice.

[1ncorrect]

Open → Input Devices and select your keyboard and mouse from the respective dropdowns.

This won't add an extra keyboard and mouse like you wanted, but it will make the system accept virtual emulated input on behalf of your physical devices.

Yeah Flame Man is right, there are games, emus and apps that support multiple keyboards and mice, you could in theory map more gamepads to multiple virtual keyboards and mice or remap them.

It is possible to remove them and send remapped inputs as if from your physical devices with keyboard and mouse functions.

Sounds interesting, how do you do that?

[FlameMan]

I know that there are games which recognize different nice and keyboards like Serious Sam. If you will remap multiple gamepad to k/m you will control only one user. But usually games which support multiple keyboards, they have good support for other input methods, so it's possible to use there Virtual DS4 for separate configuration. But maybe TestoMan has different use case like using it in emulators which ignore virtual gamepad inputs and he needs separate k/m profiles or somewhere else.

By default, reWASD uses a single keyboard and mouse devices for remapping.

But why might you need multiple virtual keyboards or mice on the same system?

[TestoMan]

reWASD can already create multiple virtual gamepads but not different virtual keyboards and mice, why is that? would be really useful.
