There are many different keyboard layouts corresponding to different languages, and usually your keyboard and the system setting will match. But you can switch to use a different layout, such as a French keyboard layout even if you are using a U.S. keyboard. You can add multiple keyboard layouts and easily switch between them. For some lanuages, like Chinese, you need to use a Chinese layout to by able to type. Once you set up multiple keyboard layouts, there are keyboard shortcuts to switch between them.
