On the keyboard of some laptops like ThinkPad, HP, etc., there is a red button, but not many people know its usefulness. So, what is the red button in the middle of the keyboard, what does it do? We invite you to learn more through the article below.
The red button is as small as a fingertip, located between the G, H, and B keys on the keyboard called TrackPoint, which often appears on some laptop lines.
TrackPoint is actually a combination of 4 compression resistors, on top is a rubber layer. This resistance will change when the user applies a force to the knob that helps you control the mouse pointer. Depending on the force of impact, the mouse pointer will move quickly or slowly.
Usually, for easy identification the TrackPoint is red but sometimes it can also be black, or green.
TrackPoint is the idea of researchers Ted Selker and Joe Rutledger and first appeared on the IBM ThinkPad 700c by Richard Sapir – one of the most important industrial designers of the 20th century.
Current laptops are equipped with a mouse or a Trackpad, but people still invented the TrackPoint to save time when switching from typing to controlling the mouse pointer.
TrackPoint is integrated right on the keyboard, so the distance will be shorter than if you put your hand down on the separate mouse or Trackpad.
