Android’s physical navigation buttons are back on Googlebooks, but not the way you think - The Verge

Automated excerpt

But there is something new for Googlebooks that’s ripped straight from Android phones circa 2014. On every Googlebook keyboard, the F1, F2, and F3 keys are the old triangle, circle, and square navigation icons that first debuted on Android 5. 0 Lollipop. These were the back, home, and app switcher buttons long before everything went to gesture-based navigation, and they’re still built into phones on Android 17 as an alternative. The back button seems sometimes necessary when using Android apps that aren’t really optimized for a desktop interface or mouse controls.
