Mouse keys

Mouse keys are like a magic trick that you can use on your computer when you don't have a real mouse or can't use one for some reason. Normally, you use a mouse to move an arrow on your computer screen and click on things like buttons or links. Mouse keys let you do all of these things using the keyboard instead.

So, imagine that instead of moving a real mouse with your hand, you use a special keyboard that has some extra buttons that act like a mouse. When you press these buttons, the arrow on the screen moves around just like if you were moving a real mouse. For example, if you press the button that says "up," the arrow moves up on the screen. If you press the button that says "down," it moves down.

You can also use other keys to make the arrow move faster or slower or to click on things on the screen. For instance, you can press a button to make the arrow move faster or slower, or to make it jump to the next button or link on a webpage.

Some people use mouse keys because it can be a useful feature if they have trouble using a real mouse due to an injury, disability or if they simply prefer this way of navigating their computer. It may not be as quick and easy-to-use as a real mouse, but it's still a great option to have.
