Can arrow keys be added to an iPhone keyboard? Is there a way to add arrow keys to an iPhone keyboard under iOS 6?
It might be possible on a jailbroken device, but not on with standard iOS. There are just no user configurable options for the keyboard, beyond adding additional languages. App developers can augment it slightly, and there are some apps with additional keys, such as Prompt and Textastic, but it's otherwise a standard system component that can't be changed.
