Last time I installed LineageOS I tried the gesture navigation and it did provide a hands-on tutorial as part of enabling it.
- Swipe up (from anywhere) to access the app tray
- Swipe up and hold to see the app history / currently in-memory apps
- Swipe from the side of the screen to go back (can be configured to just be the bottom half of the screen and a "thinner" sensitivity area - which I needed because the defaults were stupid and made 'back' such a frequent accidental action).
They're the only gestures I've bothered to learn, and I get by. Still not sure it's better or worse than have the 10 pixel space at the bottom for the navigation buttons.
