They aren't anywhere. It was a mockup.

As for correcting arrows, Here's an example of how I was thinking it would work (again, I'm just a patch monkey, so I could be grossly wrong):

User types "hellp joe".
User taps in the general area of hellp, but the cursor lands on the e ("he|llp joe").
The user presses the volume rocker down a couple of times to go to the p.
The user then presses the back arrow.

As for carriage return, I'm adding it right now :-)
