Google Keyboard is getting a pretty massive update this week, bringing a number of new features. The best one may be a new one-handed mode to allow for easier typing with… one hand (that was pretty obvious). The other updates are pretty cool, but will require a bit more digging to make the most of them because they aren’t so apparent.
One-handed mode can be easily toggled by long-pressing the comma key (where you would normally just find the Settings option,) and you can choose if you prefer left-handed or right-handed orientations, or just switch on the fly. Basically, one-handed mode shrinks the keyboard to make it easier to reach all the keys.
