What is the middle mouse button?

The mouse wheel generally refers to the part between the left and right mouse buttons. Generally the mouse wheel can slide back and forth. In addition to sliding back and forth, the four-way wheel can also tilt left and right, and the specific functions can be set by mouse driver software.

The mouse wheel is generally used when the interface has scroll bars, such as browsing web pages or documents (such as Office files). When browsing files, you can change the view of the folder by holding down the ctrl key and then rolling the wheel.
