Windows 10 has some awesome new Touchpad gestures that should make navigating the OS a lot easier. There's pinch-to-zoom, two-finger scroll, three-finger multitasking, and more. Below, gesture for zoom in and zoom out - squeeze fingers together or apart.
Some of these gestures
are customizable as well, go to Settings > Devices > Mouse
and Touchpad. You can change the actions of finger taps, adjust
scrolling, right click, and more.
