As a Roblox developer, it is currently impossible to turn the Camera using the keyboard, only with the right mouse button:

If Roblox is able to address this issue, it would improve my development experience because, in addition to being a standard of almost all games, moving the camera with the keyboard allows you to avoid using the mouse, when other functions are associated with it.
