Here is the one-handed 'Arc mode' in Microsoft's Word Flow keyboard for iOS

[Windows Central]

Last night, we revealed some of the first screenshots of the new Word Flow keyboard that is in private beta testing for the iPhone.
Today, we can add a bit more information to that including some images of the one-handed mode with the new Arc mode that is available too.

Arc mode is a one-handed option that lets users align the keyboard to the left or right side of the screen. It then curves the keyboard around presumably to shorten the distance that a user's thumb will have to reach for letters on the edge. The motion is likely more natural for the end-user due to the orientation of the keyboard when using it one-handed.
