Once upon a time, mice had balls, and there was even a joke field service bulletin telling customers how to manage them better.
Given that a defining feature of mechanical meeces was the fact they had a rubbery ball inside, it seemed obvious to early laptop designers that a trackball would make sense to move the pointer around.
Eventually the touchpad took over, and divided opinion – some people just couldn’t live without a USB-tethered proper mouse, which they carted around with their laptop, while designers sought to add more and more functionality to the touchpad.
On a Windows 10 laptop, if you type touchpad at the start screen to find the settings that control it, you’ll see a load of additional gestures have been added over time, depending on what capabilities your machine has (specifically, if it has a Precision Touchpad or not).
If you’re especially particular about how your touchpad works, you may wish to look into tuning it further through registry tweaks.
