That keybind does not make the player move and instead just forces you to move instead of interacting (or attacking i believe) when you click something.
Edit: It’s not even available when using WASD layout unfortunately, it could potentially help with the issue i reported here Issue with WASD while holding button of skill on cooldown
Edit2: There is an actual “move” keybind (not sure if it’s new, i don’t remember seeing it before), but like the “force move” it’s not available in the WASD layout.
