— touchpad (more precisely, even touchscreen in the form of an elongated panel) installed at the top of the keyboard, usually instead of the F1 ... F12 keys. Such panel is capable of displaying various controls, depending on the application currently being used. For example, in graphics editor, you can display icons of brushes and other tools on it, in media editor — graphic diagram of an audio or video file, when watching video — rewind slider and player control buttons, etc. In addition, in Apple laptops, where the Touch Bar originally appeared, it also plays the role of fingerprint scanner. Thus, the possibilities of the keyboard are greatly expanded. On the other hand, this feature significantly affects the cost.
