The keyboard is an integral part of our daily lives, and we use it to interact with our computers, type out documents, and communicate with others. While most of us are familiar with the standard keys on a keyboard, such as the alphabet keys, number keys, and function keys, there is one key that often goes unnoticed – the centre button. In this article, we will delve into the world of the centre button, exploring its purpose, history, and functionality.
What is the Centre Button?
The centre button, also known as the middle button or scroll button, is a key located in the middle of the keyboard, usually between the left and right mouse buttons or below the space bar. Its design and placement may vary depending on the keyboard model and manufacturer. The centre button is often overlooked, and many users are unaware of its existence or purpose.
A Brief History of the Centre Button

- Scrolling: In many applications, the centre button is used for scrolling. When pressed, it allows the user to scroll up or down a page or document.
- Zooming: In graphics and design applications, the centre button is often used for zooming in or out of an image or document.
- Panning: In 3D modeling and graphics applications, the centre button is used for panning, allowing the user to move the view around a 3D object or scene.
- Opening Links: In some web browsers, the centre button is used to open links in a new tab or window.
