There is a red button in the middle of THINKPAD keyboard. How to use that button? Also, what are the buttons on the touchpad?

This red button is called the pointing stick, also called Little Red Riding Hood. It plays the role of moving the cursor, just like the touchpad. Hold it in your hand, then tilt it in the direction you want to move, and you will find that the cursor on the screen moves with it.

This little red riding hood is Lenovo's patented design, which is usually used with the left and right keys on the panel. Because it has no click function, you can only use it to move the cursor. At present, most users are not used to using Little Red Riding Hood, because its response speed is usually slower than the touchpad.

However, Little Red Riding Hood also has its own advantages compared with the touch panel. For example, when operating with a touch panel, due to the limited width of the panel, when the finger slides to the edge on the panel, if the desired destination is not reached, the cursor will slide again. When operating little red riding hood, you just need to hold it down and keep leaning in this direction. The three buttons on the touchpad are the left mouse button and the right mouse button, and the middle mouse button is used for little red riding hood.

Extended data:

Because the position of Little Red Riding Hood is in the middle of keyboard letters G, H, V, B and N, and it is just in the middle of index finger and thumb when typing with both hands, you only need to use thumb and index finger to use Little Red Riding Hood. Put your index finger on the red little red riding hood and press it gently in the direction you want the cursor to move. The greater the pressure, the faster the cursor moves, and vice versa. In short, the action is simple, and you can get used to it after practicing a few more times.

The two keys in the red box of the keyboard represent the functions of the left and right mouse buttons respectively. Hold down these two keys with your thumb and move the cursor with little red riding hood, and you can get the complete mouse function.

Before the touchpad appeared, Little Red Riding Hood+two keys could replace the mouse, and they could put their hands on the keyboard. Therefore, in the past, many people played more smoothly than using touchpad and mouse, and their office efficiency was very high when they were on a business trip. For a long time, brands such as Hewlett-Packard and Dell have added the pointing stick function to notebook computers.
