How do I enable three- and four-finger touch gestures on the touch screen?
Type 'touch gesture' in the Windows search box and press Enter, then turn on the 'Three- and four-finger touch gestures' switch. These gestures allow you to show all open windows, show the desktop, switch apps, and switch desktops.
