There are several different kinds of keyboards for PCs. The most common type is a physical, external keyboard that plugs into your PC. But Windows has a built-in Ease of Access tool called the On-Screen Keyboard (OSK) that can be used instead of a physical keyboard.
You don’t need a touchscreen to use the OSK. It displays a visual keyboard with all the standard keys, so you can use your mouse or another pointing device to select keys, or use a physical single key or group of keys to cycle through the keys on the screen.
