The Nintendo Switch 2's official reveal trailer seems to confirm a rumor that the Joy-Cons can also function like a computer mouse, which would really open up the possibilities for RTS and FPS games on the console.

Perhaps more importantly, the video shows the Joy-Con clicking onto a separate piece before going into mouse mode. This other piece looks like it has some small pads on the bottom, like a computer mouse would, to make it a little easier to slide around.
