AI Summary

Googlebooks keyboards now feature the classic Android navigation icons—triangle, circle and square—mapped to the F1, F2 and F3 keys. These symbols originally appeared on Android 5.0 Lollipop as back, home and app‑switcher buttons and persist as an optional scheme on Android 17. On Googlebooks, pressing the triangle returns to the previous screen, the circle minimizes all open apps, and the square displays open apps in a view similar to macOS Mission Control or Windows Task View. The Quick Insert and Google logo keys are not new, having debuted on some Chromebooks years earlier.
